Is this stuff less prevalent in other fields? In tech, you never realistically need to worry about money or losing your job (as it is so easy to find another) - most people don't have this comfort. IMO tech is an excellent career. Just don't become a big spender so that you have to work till your sixties.
It is more prevalent. People in tech also work long hours, have "side projects" aka somewhat expected unpaid work, are unhealthy, seem to not exercise, play video games too much, watch too much tv...
Is it more prevalent because we have hard data showing it is, or do we think it is more prevalent because we typically speak with more people in tech because we're in tech and have more experience with them?
I am now a few years post-divorce and in a relationship with a wonderful future wife v2.0, and I will be the first to tell you that my perspective on others', careers, and behavior patterns has changed significantly because I'm exposed to a very different slice of American culture than I was with wife v1.0. You'll find similarities where you didn't expect to find them. The same is true of differences.
Still lower than a lot of other professions. I do wonder how the difference in work-culture affects the data though. I have talked to programmers in the UK who say that the environment is completely different -- 35-40 hour weeks rather than the churn and burn that you see at a lot of businesses here.
Mabey this is more an American problem? I live in Sweden and developer jobs here are fairly low pressure, high pay and everything else the rest of the industry has: 1 year maternity leave, 6 week paid vacation etc. I would definitely recommend it to anyone!

This is a misconception. If you work in a cost-centre (biz speak for not making direct dollars) your task maybe cut. I've seen whole divisions in corporations cut when savings were required. Startups are notoriously flakey for employment for reasons other than direct failure. If you work in an area with measurable sales (product) you may make a lot of money.
Tech at the moment reminds me of Rock music in the 70's. Lots of cash splashing about, deals done, people making money in making music. If there is a re-adjustment due to technology, for example the move to coughDigital/CDscough in the 80's using our music analogy?
