Here’s a letter to political-science student Brandon Mortensen:
Mr. Mortensen:
You’re correct that “economic theory identifies conditions” under which labor-market interventions by government – such as minimum wages or mandated paid leave – when performed ideally “increase social welfare.” But it’s incorrect to conclude that these theoretical possibilities “delegitimize [my] stance opposing all these interventions.”
In the past I’ve explained why I believe that not all theoretical possibilities justify policy actions. See, for example, here [2], here [3], and here [4].
Let me, though, try again.
It’s easy to describe conditions under which social welfare will be increased by permitting government officials to summarily execute – without trial, warning, or even explanation – sleeping individuals. Such a policy plausibly passes a cost-benefit test if we simply assume that government officials invested with such permission will summarily execute only individuals who otherwise, after waking up, would commit mass murder.
Such a constructive use of this power is theoretically possible. Yet I trust that you don’t find that this theoretical possibility “delegitimizes” my – and, I presume, your – stance against government officials summarily executing without restriction whichever sleeping persons they wish. In this case, you correctly recognize two features of reality that justify a policy of blanket and unyielding prohibition of such executions: (1) although our real-world often has in it sleeping individuals who, after awakening, will commit mass murder, it’s impossible in practice for government officials to identify such persons; and (2) even if government officials did possess the knowledge and information of god, they possess the self-interest and weakness of humans.
I don’t mean to ethically equate labor-market interventions with a government policy of such summary executions. But I do mean to insist that the theoretical conditions necessary to ensure that social welfare will be improved by labor-market interventions are no less unrealistic than are those necessary to ensure that social welfare will be improved by summary executions of people in their sleep.
