Fixed-Rate Fictions
Governments, especially including the US. government, seem to be congenitally incapable of keeping their mitts off any part of the economy. Government, aided and abetted by its host of apologists among intellectuals and policy wonks, likes to regard itself as a deus ex machina (a "god out of the machine") that surveys its subjects with Olympian benevolence and omniscience, and then repeatedly descends to earth to fix up the numerous "market failures" that mere people, in their ignorance, persist in committing.
