Mobility can constrain majority power—but it must not give the most mobile people more political power than everyone else
Suppose 60 percent of voters support a law.
The law is enacted.
Majority rule is central to democracy.
But democracy is more than majority rule.
The previous article described political captivity: people may possess substantial democratic freedom within a political community while having little meaningful freedom over which political community they can eventually belong to.
That condition matters for majority power.
If almost everyone is effectively tied to the political community into which they were born, a majority governs people who may have few realistic political alternatives.
Foot Democracy changes that background.
But it creates another problem.
What happens when some residents can leave much more easily than others?
Can mobility discipline majority government without giving the most mobile residents more political power?
That is the question here.
Rights Come First
One boundary can be stated briefly.
Earlier in this series, I argued that neither majority approval nor the availability of Exit can justify a violation of basic rights.
That principle does not change.
A majority cannot defend discrimination by saying, “You voted and lost.”
Nor can it say, “If you dislike it, leave.”
Foot Democracy becomes relevant after that constitutional boundary is secured.
Its role is not to decide what rights a majority may violate.
Its role is to change the incentives and alternatives surrounding political choices that remain legitimately open to democratic decision.
Two Kinds of Discipline
There are therefore two different ways in which majority power can be constrained.
The first is constitutional discipline.
Rights, legal procedures, courts, review, and other constitutional institutions limit what a majority may legitimately do.
The second is mobility-based discipline.
If residents have meaningful alternatives among political communities, governments may face pressure from the possibility that some people will choose to live elsewhere.
The distinction matters.
Constitutional discipline limits authority.
Mobility-based discipline changes incentives and alternatives.
If a majority violates a basic right, the answer is not to wait and see whether enough people leave.
But if a majority makes a legitimate policy choice about taxation, housing, transport, or public services, mobility may become part of the political environment in which that decision operates.
Norway: When Exit Becomes Political Leverage
Norway provides a useful example.
Norway has long imposed a tax on net wealth.
During a series of tax reforms from 2021 through 2024, effective taxation of business wealth and dividends increased.
Some wealthy residents subsequently moved abroad, and moves to Switzerland became prominent in the public debate.
That movement mattered politically.
Governments care when taxpayers, investors, business owners, or highly skilled residents leave.
Even a relatively small number of departures can become highly visible.
This looks like mobility-based discipline.
Government makes a decision.
Some residents have an alternative.
They use it.
The government must then decide how much political meaning to attach to their departure.
But the example immediately raises another question.
What if those most capable of leaving are also among the wealthiest and most economically influential members of the community?
Departure Is Information, Not a Verdict
One response to the Norwegian case would be simple:
wealthy people left, therefore the tax policy failed.
But the evidence does not support so simple a conclusion.
A 2026 NBER study by Marius A. K. Ring examined Norwegian tax reforms from 2021 to 2024.
It found clear migration responses among the very wealthy, concentrated especially among the top 0.1 percent and largely in 2022 and 2023.
But the estimated scale was much smaller than the public language of an “exodus” might suggest.
The study estimates that at most about 100 people left because of the reforms.
It also estimates that, without reform-induced outmigration, wealth-tax revenue would have risen by about 75 percent between 2021 and 2024.
After accounting for that outmigration, the increase was still about 71.5 percent.
The study also found no evidence that the affected firms reduced investment as a result.
That does not prove that every feature of the policy was optimal.
Nor does it prove that migration responses do not matter.
It shows something narrower and more important for this article:
Departure is information. It is not a verdict.
A government should notice when residents leave.
It should ask why.
It should examine the fiscal consequences.
It should consider unintended effects.
But movement does not replace political judgment.
A majority may know that some residents will leave and still rationally choose the policy.
When Government Responds to Exit
Norway’s response reveals the other side of the problem.
In 2024, Norway strengthened its exit-tax rules for unrealized gains when individuals cease to be Norwegian tax residents.
The stated objective was to preserve Norwegian taxation of gains accrued during Norwegian tax residence rather than allowing those gains to escape taxation simply because the owner moved abroad.
For emigrating individuals, the revised rules also introduced a NOK 3 million tax-free allowance.
The government explicitly noted that this allowance could mitigate possible negative effects on mobility.
This creates a difficult question for Foot Democracy.
A political community may have a legitimate interest in maintaining tax claims connected to gains accumulated while a person lived under its institutions.
But a tax triggered by departure can also affect the practical freedom to leave.
So where is the line?
When is an exit tax a legitimate way to preserve an existing fiscal claim?
When does it become a disproportionate obstacle to Exit?
Foot Democracy does not provide an automatic answer.
Both interests have to remain visible.
Freedom to leave does not imply freedom to erase every obligation created before leaving.
But neither should a government be able to make departure prohibitively costly simply because it wants to keep residents inside its tax base.
When Mobility Becomes Extra Political Power
Now imagine two voters.
Both have one vote.
One is wealthy, internationally connected, owns liquid assets, speaks several languages, and can establish residence elsewhere quickly.
The other has an ordinary income, cares for an elderly parent, depends on a locally specific job, and has children established in local schools.
Formally, both may possess the same freedom to leave.
Practically, they do not.
Now suppose the government considers a tax increase.
The first voter can credibly say:
If you adopt this policy, I can move.
The second voter cannot make the same threat.
At the ballot box, each has one vote.
Outside the ballot box, their mobility gives them different leverage.
This is the democratic danger.
Foot Democracy is meant to increase political freedom.
It should not create a system in which the most mobile residents acquire a second, unofficial vote.
Equal membership inside a community must not depend on how credible a person’s threat of Exit is.
The Exit Threat Is Not a Democratic Entitlement
Political influence is already unequal in many ways.
People have different amounts of money.
Different networks.
Different access to officials.
Different organizational resources.
Different ability to attract media attention.
Mobility can become another source of unequal influence.
That does not mean governments should prevent people from leaving.
Nor should mobility be deliberately made difficult simply to equalize political leverage.
But governments should not confuse a credible Exit option with greater democratic standing.
A person who can move easily does not thereby acquire a stronger claim to have public policy designed around their preferences.
Otherwise Foot Democracy would work against Resident Equality.
Formal equality at the ballot box would coexist with an informal hierarchy based on mobility.
How Should Government Read Exit?
The answer is neither to ignore Exit nor to obey it.
Governments should treat movement as evidence.
If taxpayers leave after a policy change, that matters.
If families leave because housing becomes unaffordable, that matters.
If professionals leave because institutions deteriorate, that matters.
If new residents arrive because a community provides opportunities unavailable elsewhere, that matters too.
But these are inputs into democratic judgment.
They are not commands.
Government still has to ask:
What are the policy’s benefits?
Who bears its costs?
Who gains?
Who leaves?
Who cannot leave?
Are costs being shifted onto another community?
Is the policy sustainable?
Are there less damaging ways to achieve the same objective?
Foot Democracy can make these questions harder to ignore.
It cannot answer them automatically.
Exit Can Strengthen—or Weaken—Voice
Mobility can improve democratic politics even when people do not move.
Residents can compare neighboring communities.
If similar services cost much more in one place, voters can ask why.
If one city builds housing while another remains chronically short, residents can compare the rules.
Visible alternatives can sharpen public debate.
In that sense, Foot Democracy can strengthen Hand Democracy.
But Exit can also weaken Voice.
If the people most able to organize opposition, finance civic organizations, or supply professional expertise leave first, those who remain may become less able to reform the community.
Sometimes Exit and Voice reinforce one another.
Sometimes one weakens the other.
The important question is not merely whether Exit is possible.
It is what Exit does to political power both for those who leave and for those who remain.
Discipline Without Veto
Foot Democracy does not give mobile residents a veto over majority rule.
A political community is entitled to make collective choices.
It may choose higher taxes, more redistribution, stronger environmental regulation, larger public services, or different housing rules.
Some residents may dislike those choices.
Some may leave.
That does not mean democracy failed.
Nor should a government design every policy to maximize resident retention or tax revenue.
The discipline created by mobility is weaker—and more useful—than a veto.
Movement reveals consequences.
It makes alternatives visible.
It creates comparison.
It may create pressure to explain, reform, or defend a policy.
But the decision remains a democratic one, bounded by rights and equal political standing.
This produces a two-sided constraint.
A majority should not assume that everyone born under its authority must remain politically tied to it forever.
But mobile residents should not be able to convert their greater ability to leave into greater political rank.
Conclusion
Can Foot Democracy discipline majority democracy?
Yes.
But not by replacing constitutional rights.
And not by turning the most mobile residents into a privileged political class.
Norway illustrates both sides.
Exit can be real.
It can affect political debate.
It can lead governments to reconsider tax design.
Government may in turn try to preserve fiscal obligations that would otherwise disappear when residence changes.
Yet the fact that people leave does not itself decide whether the original policy was right or wrong.
Departure is information, not a verdict.
Foot Democracy works only when two principles remain together:
people should have meaningful alternatives among political communities;
and equal membership inside a community must not depend on how credible a person’s threat of Exit is.
A majority may govern the community.
It should not own the political future of everyone born into it.
Notes
Earlier in this series, “Rights Before Choice: Why Neither Majorities nor Mobility Can Override Basic Rights” argued that majority approval and the availability of Exit are both insufficient to justify restrictions of basic rights. This article begins after that constitutional principle is accepted.
The distinction between constitutional discipline and mobility-based discipline is analytical. The first concerns legal limits on majority authority. The second concerns incentives, comparisons, and alternatives created when residents possess meaningful political-community choices.
Statistics Norway, Taxation of the Rich and Incentives for Investments: The Case of Norway, Discussion Papers No. 1001 (2023), discusses Norwegian capital-income and wealth taxation and the contemporary debate surrounding wealthy investors and international mobility.
Marius A. K. Ring, Taxing Entrepreneurial Wealth: Evidence from Norway, 2021–2025, NBER Working Paper No. 35854 (2026), analyzes reforms during 2021–2024. It finds migration responses concentrated among the wealthiest residents, estimates at most roughly 100 reform-induced departures, and estimates that wealth-tax revenue rose substantially even after accounting for this outmigration.
Norwegian government materials on the 2024 exit-tax amendments state that the principal objective is to preserve Norwegian taxation of unrealized gains accrued during Norwegian tax residence. For emigrating individuals, the reform introduced a NOK 3 million tax-free allowance; the government explicitly noted that this could mitigate negative effects on mobility.
The exit-tax discussion here does not conclude that exit taxation is inherently justified or inherently incompatible with Foot Democracy. It identifies a conflict requiring institutional justification: preserving legitimate fiscal claims without making departure disproportionately difficult.
The discussion of Exit and Voice draws on Albert O. Hirschman. Exit may sometimes reinforce Voice through comparison and political pressure, while selective Exit may also weaken the political capacity of those who remain.
