I think you might be underestimating the level of pay for developers in a lot of the "big" areas. (SF, Silicon Valley, NYC) I've personally heard of friends (fresh college grads) getting offers anywhere from $70k to $150k.
As a fresh college grad from a non-top tier school in Silicon Valley, many of my friends are making ~$100K/year right out of school. I'm sure people from top tier schools going to Google and Facebook can make double that.
