We have un Godly large bureaucracy and in many industries is ran by the corporations that they regulate meaning there's an absence of a free market. So, USDA, FDA, DEA, ATF (all they're good for is funneling guns into Mexico), EPA, DEA (especially), FEMA...to name a few.
Believe it or not, there was a time in American history where we didn't have all these and we were just fine. In theory they would work ok but conflict of interests ruins everything.
Privatizing education (which I realize will never happen) would be nice too.
