 Imagine someone, Charlie, who has very high earnings potential. In order to ensure that everyone has reasonable access to a social minimum, the state announces that it will tax 50% of whatever income Charlie earns, and use the funds to raise the incomes of those with low earnings power. The libertarian, including the left-libertarian, will object that this violates Charlie’s rights of self-ownership. Should Charlie choose to work, half of their earnings will be funneled to others, and thus, if they choose to work, they have no choice under this tax regime but to assist others. In this way, the tax system may be said to “harness” Charlie’s talents and energies for the good of others. This effort-harnessing, alleges the libertarian, is inherently wrong; it puts Charlie in a position that is akin to that of a slave, forced to work for the good of others (Nozick 1974: 169).
