I have to disagree with this. Most IT jobs in the U.S. aren't 9-5. Every place I've interviewed have always hinted at the fact that it's not a 40 hour a week job. This may sound jaded, but companies really do expect to get more than what they pay for, and it's not just the silicon valley ones. I think the real issue is that most programmers feel a dedication and passion to what they do and they want to see the project succeed, and so the get taken advantage of.
