Earlier quoted context omitted.
As a software developer with several years in Boston and DC each, I can tell you 100k does not allow for a mortgage on a SFH within a 20 minute commute to work in either place, which is basically the american dream. Boston is even worse, the available real estate is all older and smaller and nearly as expensive as SF. I'd say feature for feature your money probably goes further in SF than in Boston.
You can certainly do this in Chicago. Especially if you're flexible on the commute time and can handle an hour on the train. The suburbs also have developer jobs.
But we shouldn't have to be flexible with an hour commute on a train while at the same time being told we live a life of luxury and are over paid. It appears to me the cognitive dissonance going on here similar to the SF people who say "It's not so bad, I found a studio for 2k/month in Oakland!"
If we were truly overpaid and in such demand we wouldn't live in crappy studios or be priced out of the neighborhoods we work in.
