To me one interesting thing about this article is that -- relating specifically to the question of whether you can get rich by picking a "safe" job -- it is actually incorrect. The changes in corporate compensation practices are such that, particularly in financial industries, you can work in a everyday job and end up rich, even by the definitions he uses in this article. It will be interesting to see if that continues after the current crisis. I would have guessed no a few months ago, but now it is seeming more likely to continue.
