If you honestly believe this, then you are living a very privileged life. Be happy about that, because it is very lucky.
Those salaries _can_ be found in other areas of the country, but they are almost completely concentrated to tech hubs of the country. Lots of cities throughout the country don't have these jobs.
I don't live in a tech hub. The only place I've lived that was close was Northern Virginia (for only two years) and I hated it so much I moved to Florida.
I graduated from a fairly average state university with a BSCS in 2002 and joined the Army. My first software engineering job (which was hard to land given I had gone 4 years since college doing something completely different) paid $55k in 2006. I crossed the $100k threshold in 2012.
Though, I'll admit the raises haven't been as generous the last few years, and I did have to move a few times for jobs :)
But I really don't think my life has been particularly privileged or out of the ordinary for a reasonably competent developer (and many here on HN who do live in tech hubs make quite a bit more than I).
