"Buy America" (we've always thought this particular version of patriotic claptrap somewhat unfortunately spelled) provisions haven't exactly been a popular notion, but we wouldn't go so far as to compare them with addictive stimulants (though this depends on the stimulant). Others seem to have no issue with throwing around the C-word. To wit:
Dallas Federal Reserve President Richard Fisher warned on Monday against "Buy America" provisions in a proposed fiscal stimulus law and said it could lead to devastating trade protectionism.
"Let me just be blunt. Protectionism is the crack cocaine of economics. It may provide a high. It's addictive and it leads to economic death," Fisher told C-Span television in an interview for its "Washington Journal" program.
Well, it made headlines, so he's got that going for him.
