CRONY REGULATION: Tim Carney: To protect restaurants, D.C. may curb food trucks. “D.C.’s restaurant lobbyists, along with many local politicians and bureaucrats, seem to think the government’s job is to save the delis and diners, bistros and brasseries from the scourge of falafel trucks, barbecue buses and weenie wagons. . . . Barriers to entry are a great way to protect incumbent businesses and thus allow for higher profit margins, but you wouldn’t think politicians would actually put value on protecting the restaurants from competition. In D.C., though, the politicians do.”
