Good article. I would suggest not leading off with the current first two points (Egos + No-men), as I think the extent to which each of these is true varies between labs / disciplines, whereas the other three points seem to be more or less universal throughout science.

(I have personally been lucky enough to never run into the Ego / No-men problem with any of my advisors; for a while I thought everyone who complained about these things was being melodramatic, but as some point a critical mass of highly reasonable people made such claims that I now believe them.)

I also think you overstate some of your claims, which may be suboptimal given that your points are already strong without the overstatements (for instance, the $60k number is high, even before you take into account the large amount of financial aid that universities provide; even with no financial aid, MIT only costs $55k/year, for instance, as far as I can tell).
