Most investment banking analysts aren't doing the job for the pay (which is mediocre when the hours are considered) but the exit options, one of which is VC. Investment bankers are, on the whole, mediocrities if not outright idiots; the analyst position enables the talentless to trade in their health and well-being in order to have career options that would otherwise be way out of their league. Thus, many venture capitalists are former investment bankers.
Anyone see the problem here?
