The limits of the law, the socioeconomic bias in turnout, and the justification of compulsory voting

Resumé

Since nonvoting is concentrated among badly off electors, the introduction of compulsory voting will raise electoral turnout among badly off electors more than among well off electors. Therefore, compulsory voting increases the political influence of the worst off. This well-founded empirical claim is central to the two most prominent arguments in favor of compulsory voting. According to both arguments, compulsory voting is justified because of the good consequences of increasing the political influence of badly off electors. It is, however, not possible to justify compelling well off electors to vote on the grounds that it is desirable to raise turnout among badly off electors. Therefore, both arguments fail.
