I personally know several people who have been taken advantage of by their professors, so I'm inclined to believe him.
Also, "taken advantage of" is exactly the right term in my friends' cases. Both are classic Aspergers cases (actual Aspergers, not just an excuse for bad behavior), and their professors seem to be taking advantage of the trouble they have mounting an effective resistance.
That's just the real world calling, and their refusal or inability to answer. If they were in corporate america, a co-worker or middle manager would steal their work and take credit, or capitalize on their inability to resist additional assignments.
If they were in a start-up, they'd be overburdened and then forced out, probably receiving the lowest equity of anyone and getting even less than out of the deal, because they didn't make any decisions.
Its just a dog eat dog world out there, and if you can't say "No" or take credit for your achievements, you're going to get taken advantage of.
I've worked in corporate America for a while now, and I haven't seen managers steal credit for their workers work before. Generally, if you're a manager and you have someone you manage who is doing a great job and getting lots of stuff done, that reflects well on you as a manager too.
I've also worked in places where engineers get the offices with windows, there are lunchtime tech talks, and managers try their best to prioritize work and then "get out of your way".
So it all depends. The people who email Scott Adams (of Dilbert) their workplace horror stories are not [all] making them up. A "good" corporate culture in America is still atypical, IMHO.
As for your friends, who's to say that academic science is the culprit? There's assholes everywhere, and neither you, nor the GP has convinced me it's endemic to science research.
As for my anecdote, I work in bioinformatics now. I've only just started, but so far my experience couldn't be more different.
