Ludwig von Mises had a theory about interventionism. It doesn't accomplish its stated ends. Instead it distorts the market. That distortion cries out for a fix. The fix can consist in pulling back and freeing the market or taking further steps toward intervention. The State nearly always chooses the latter course, unless forced to do otherwise. The result is more distortion, leading eventually, by small steps, toward ever more nationalization and its attendant stagnation and bankruptcy.
