A big problem with filthy rich outfits is that they can simply afford to do this. My two highest-paying jobs were almost sinecures. The teams were massively overstaffed, and it could be quite difficult to find productive things to work on. I spent a lot of time simply waiting, which is to say killing time.
If your goal in life is to be rich, it's not bad, I guess. If you really love doing good tech, it's stultifying.
