My comment on the Christopher Hayes discussion over at TPM Cafe:
It's Different for Lefties and Righties | TPMCafe: My view is that the neoclassical economics toolkit can be very, very useful--no, stronger than that, is very useful and necessary--for everybody from the center on left. The methodological individualism of the toolkit forces you to look at real people and how situations help or hurt them. The competitive market benchmark assumed by the toolkit requires you to think carefully and specifically about just where the externalities are that keep you from relying on markets alone to solve whatever problem you are looking at. The equilibrium conditions established by the toolkit force you to check for unanticipated consequences, for blowback due to changes in incentives and so forth.
The result is that the neoclassical economics toolkit makes you a smarter, stronger, more powerful, more effective, more reality-based leftie.
By contrast, the neoclassical toolkit can be absolute poison for people right on center. It functions like a kind of crack, reducing their arguments to empty slogans: "the market takes care of that"; "acts of capitalism between consenting adults"; "they hired the money, didn't they?"; "it's not the government's, it's theirs."
People right-of-center should be exposed to the neoclassical economics toolkit only after posting a $1M bond to cover collateral damage, and only under the supervision of trained professionals.
