These companies are exceptional. In fact, one could argue (and it has been argued) that these companies should divest themselves of their cash because almost by definition they are being inefficient. Although there are 10's of thousands of people who work in companies like these, there are millions of people who do not.

I have some experience working at a large company where many of the employees' main motivation was to lay claim to a piece of the company pie. I'm fairly certain that my cautionary advice is not misdirected even in that circumstance.

YMMV and if you never experience the problems I write about, then I will be very happy for you ;-)
