critique of pure reasonableness

Paul Krugman found irrationalities
in how the market evaluates stocks
"buy low sell high" is naive piety
more honored in the books than by the flocks

capitalism is prone to excess
and equilibrium's a shallow well
when ego enters, what you get's a mess
and Adam Smith's too-neat world goes to Hell

professor Reich points out one must step back
no markets operate without a State
it's laws that fill what rules of econ. lack
to get the price the numbers indicate

the fundamentalists are up in arms
but laissez-faire is doomed to cyclic harm
