Birth tourism
Some countries do not allow their citizens to renounce their citizenship or only if the citizenship was acquired by birth there to non-citizen parents. In Argentina, Brazil, Ecuador, Peru, and Uruguay, voting is compulsory for citizens. In Bolivia, Brazil, Chile, Colombia, Cuba, Guatemala, Paraguay, and Venezuela, military service is mandatory.
Compulsory voting
Supporters of compulsory voting also argue that voting addresses the paradox of voting, which is that for a rational, self-interested voter, the costs of voting will normally exceed the expected benefits. The paradox disproportionately affects the socially disadvantaged, for whom the costs of voting tend to be greater. Australian academic and supporter of compulsory voting, Lisa Hill, has argued that a prisoner's dilemma situation arises under voluntary systems for marginalised citizens: it seems rational for them to abstain from voting, under the assumption that others in their situation are also doing so, in order to conserve their limited resources. However, since these are people who have a pronounced need for representation, this decision is irrational. Hill argues that the introduction of compulsory voting removes this dilemma.
