Bad things happen when petty people have arbitrary power. Any part of the U.S. government that deals with foreigners (foreigners without lobbyists, to be precise) is likely to become abuseive because the foreigners don’t have Congressmen to complain to. The only solution is vigorous inspection and high-quality public management, starting with a President who throws a well-publicized tantrum every once in a while to remind the civil servants that civility is part of their job title.
