Or d) they are willing to move out of the top 5-10 mostly coastal real estate markets. For instance, tech hub Austin, TX has a median home price of $122k. The payment on that will be around $1k-$1100/mo including taxes etc. You'll find very similar numbers in places like Atlanta, Houston, Dallas, Raleigh, etc.
That's a valid point, but I didn't know there were any tech hubs or otherwise interesting places with jobs that had house prices like that. That is lower than small Midwestern cities with lousier economies. Why is housing so affordable in Texas? Lack of stupid regulations? Loads of land?
If you're willing to live outside a tech hub (which has other advantages), you'll find that in most places in the US programmers make high salaries relative to the cost of living, but the focus tends to be on the few places that this is not true. Outside the top markets, $70k + bonus is more than enough to be comfortably middle class (and own a home and car if desired).
