Then why the hell do you? To make someone else rich? To help VCs get a few extra dollars? Slave away with 60 hours weeks for years only to see an exit that nets you less than what you could have made working for any of the big companies? So that you can experience wanting to move on after a few years but worrying about losing stock options? SO you can sit around wondering when the company is going to IPO and you can actually make some cash? (meanwhile the CEO cashed out years ago, and doesn't want to IPO ever)
Seriously though, I feel the tone and attitude you're satirizing are describing the startup culture pretty well.
The equity has never made up the loss of salary. As an employee your company has to become really, really big for it to be life changing and that's incredibly unlikely to happen for all but one or two startups every few years and there are many thousands of startups. As an employee working at a small startup can't be about the money, if it is then you are wasting your time.
If you're good, you can advance much more rapidly through startups and then parlay that experience into either a lucrative BigCo job or consulting gigs.
