We take it more or less rightly as a given that people in finance will have generally right-leaning politics - low taxes, tight money, lax regulatory regimes. Basically traditional money Republicanism. But over the last few years (since 2008), I think there's been a pretty dramatic growth in what we'd call Tea Party politics in that set - extreme conservatism that goes beyond hands off fiscal and regulatory policy, the kind of feverish mindset in which you could write with a straight face that progressives might be building toward some sort of mass wealth confiscation or internment or even extermination for the likes of Tom Perkins.
It's a problem. And Perkins is just getting our attention because his self-censor and/or editor failed him so miserably.
A very interesting read on the Perkins diatribe.
