Nothing stifles prosperity like regulation:
The growth of federal regulations over the past six decades has cut U.S. economic growth by an average of 2 percentage points per year, according to a new study in the Journal of Economic Growth. As a result, the average American household receives about $277,000 less annually than it would have gotten in the absence of six decades of accumulated regulations—a median household income of $330,000 instead of the $53,000 we get now.
