I think someone's skewing the poll.

Personal wealth follows a powerlaw distribution, and there's good reason to believe that income from stock options is somewhat similar. If you look at the numbers above they make reasonably sense except for the "in the hundreds of millions" which is far too high compared to the others. The "in the hundreds" and "in the thousands" should be higher, but I'd wager that that can be explained by people not getting stock options in the hundred or thousand dollar range. The paper work alone would cost more. It's expected that there are a few, since a stock can tank, so stock options initially worth millions can turn into thousands when cashed in.
