Sheffield traced the paleo-libertarian movement — which is essentially a merging of free-market fundamentalism and far-right cultural populism — back to the “anarcho-capitalist” economist Murray Rothbard, who is famous for, among other things, advocating child labor and claiming that parents should have the legal right “not to feed [their] child [and] allow it to die.” Rothbard was a co-founder of the Koch-funded think tank Cato Institute, and later the Ludwig von Mises Institute, which “enabled the fledgling [libertarian] movement to establish affinity with the neo-Confederate Lost Cause movement.”
