Now, some will say that he, the CEO, is already independently wealthy (having owned a hedge fund and being worth around $700m) and just took the job for the prestige, but it's been the same with the previous directors - only they weren't loaded.
Others will also argue that, hey, it's just a pension fund - their goal is not to innovate, or beat competitors, they just manage the money in a way that keeps up with the market, and mainly manage risk.
$650k a year is what, VP salary in some no-name hedge fund or private equity firm? Small business CEOs are making more than that.
But some people are taking that job, and doing it just as well as their competitors at fund with 0.01% of the AUM, but at 1%-0.1% of the salary.
