Not all of them. I'd have more trouble finding work if it was true. By the way, IME Eastern Europe is the best outsourcing destination if you want good quality for somewhat less money. There are not so good companies as well, but the only good "outsourcing code" I have seen was from there.
I think it's really mostly mechanical engineering companies that undervalue software. My main client is one, they actually do value software so it's a decent environment. Unfortunately still rare.
