I think this guy has a point, but it's not actually a rebuttal to the elite overproduction thesis, it's more like "for this one angle of one piece of the elite overproduction issue we could actually do something." There are lots more people with PHDs that get pushed out of the academic research career direction they might have aspired to. And if more of them could successfully follow their dreams it'd probably be good. But that doesn't seem like a rebuttal to me.
