Instead of pushing for "constructive" free market reforms, libertarians should doggedly focus on austerity: opposing spending increases, and pushing spending cuts. Instead of trying to "privatize" Social Security, for example, libertarians should push for lower benefits, a higher retirement age, and means testing. Instead of pushing for school choice, libertarians should try to restrain/shrink education budgets and push user fees. If libertarians have any political success, this will automatically expand the role of the market. After all, the less government does for people, the more they will do for themselves. Dissatisfied with government provision, people will save more for their own retirement and spend more on private education. In the limit, once the flow of government money ceases, voluntary exchange is all that’s left.
