Slippery slope

Interventionism cannot be considered as an economic system destined to stay. It is a method for the transformation of capitalism into socialism by a series of successive steps.

There are only middle-of-the-roaders who think they have been successful when they have delayed for some time an especially ruinous measure. They are always in retreat. They put up today with measures which only ten or twenty years ago they would have considered as undiscussable. They will in a few years acquiesce in other measures which they today consider as simply out of the question.

—Ludwig von Mises, "Middle-of-the-Road Policy Leads to Socialism"
