I took the OP to mean "lacking in empathy, contextual awareness, and premised on a specific—and potentially very damaging—notion of capitalism." Based on the interviews I've read and the description of the Thiel fellows, this seems like a fair characterization, if hyperbole.
Rather, I think "sociopathic" is deficient in that it underplays the structural determinants of such behaviors, while placing judgment on the fellows themselves. That's not fair—they are basically high schoolers, often without the cultural capital and social analytical skills conferred by top schools.
