Once you step out of a small number of markets, the price problem goes away. I live in a well sized metro in the midwest, and I've worked, from here, for companies you've heard about. 4 bedrooms in my street, sitting on half an acre and a decent school district, are $250k. A 1 bedroom apartment would be under a thousand a month to rent, and that's a modern building with good appliances, a gym, a pool and gigabit internet. A single person in tech, right out of school, can easily save enough to get a mortgage in their first year working.
So yes, your situation is very real, but if there was less pressure to be in Seattle, NY or SF, the housing problems would melt.
