I absolutely disagree. With YCombinator and the dozen similar programs out there, the traditional barriers to starting companies, namely "not knowing what you don't know" are being removed. For a web start-up especially, the only cost associated with the startup for a group of young founders is time.
The goal at Google, Goldman Sachs, and McKinsey is to recruit top talent, and give them enough money and benefits that they are completely content and never have a reason to leave. Some still will, but most are probably destined for a career as a middle manager.
Maybe this is true at Google, but you need a fair amount of dedication to stick around at Goldman or McKinsey. Nobody becomes a career middle manager there. Well, maybe some back-office jobs at GS.
According to friends at Goldman, it's quite easy to be a career middle manager at Goldman in IT. There are many people there for 20+ years, the only job they've ever had.
I've been told that McKinsey has an "up or out" culture (get promoted or leave).
