An essential point in the social philosophy of interventionism is the existence of an inexhaustible fund which can be squeezed forever. The whole doctrine of interventionism collapses when this fountain is drained off. The Santa Claus principle liquidates itself.
They tell us that the government can spend and spend without taxing at all, that it can continue to pile up debt without ever paying it off, because "we owe it to ourselves". Such pleasant dreams in the past have always been shattered by national insolvency or a runaway inflation. All government expenditures must eventually be paid out of the proceeds of taxation and inflation itself is merely a form, and a particularly vicious form, of taxation.
Governments are like primitive cannibals feasting on a great treasure trove of sheeple. You can't force them out, and you can't vote them out. But you can sure as hell starve them out. When enough people pick up and leave, essentially voting with their feet, it accelerates the system crash.
No very deep knowledge of economics is usually needed for grasping the immediate effects of a measure; but the task of economics is to foretell the remoter effects, and so to allow us to avoid such acts as attempt to remedy a present ill by sowing the seeds of a much greater ill for the future.
