The idea of providing a guaranteed minimum income to every American currently lies outside the ever-shifting window of politically plausible policy ideas. But it is hardly a fringe proposal. Various public thinkers from Friedrich von Hayek to Martin Luther King Jr. have supported the idea.
There are a variety of good practical arguments in favor of providing a guaranteed minimum income, including that it would decrease economic inequality and all of its negative externalities; strengthen families, since poverty is one of the greatest contributors to family breakdown; encourage investment in personal capital, innovation, and risk-taking, because all of these are more likely when a person is not faced with uncertainty about basic economic needs; and be more efficient than the tangle of programs that currently make up the safety net. The limited empirical evidence regarding guaranteed minimum incomes also seems to suggest that their disincentive effect on work is not as serious as might be feared.
What interests me, however, is the way that a guaranteed minimum income fits together with the post-Reagan-era vision of government sketched in previous posts. The key is recognizing that because of the centrality of the price mechanism to the efficient functioning of markets, wealth inequality in and of itself represents a non-self-correcting source of inefficient outcomes—a “market failure.”
