First of all your math is way off. If you figure the average IT worker gets $50k (which is probably low for IT) then 100x would be 5 million, which is more than many of these guys on the list are making.

Second, If devoted your life to creating and building a company, and you are successfully providing a very good living for thousands of employees, yes, I think the CEO/CIO should deserve to get a high salary as long as it is coming out of the profits and not by robbing pension funds or illegal means.

Nobody is forcing any of these people to work for them & they're free to join some other company or start their own at any time they like. The IT job market is doing well and a skilled IT doesn't have to put up with a crappy job.
