Benjamin Franklin on Minimum Wage

From Freakonomics:

Benjamin Franklin apparently understood the notion that input prices affect product prices, which is a problem because product demand curves are not completely inelastic. Discussing a minimum wage, he noted, “A law might be made to raise their [workers’] wages; but if our manufactures are too dear, they might not vend abroad.” This is one of the best arguments against a minimum wage: in an open economy, which the U.S. increasingly will be at least partly passed on in the form of higher product prices, which will in turn reduce product demand—and eventually employment.

Particularly relevant when legally mandated wages are not a reflection of productivity.
