Plenty, outside of the usual suspect locations (SF, NY). A six figure salary for devs, senior or otherwise, is unusual outside those areas. It's not unheard of, but it's not typical, either.
I'm not convinced the $150K+ salary figures I see sniffed at on HN as "bare minimums" are quite as common even in SF/NY/etc. as people imagine they are. Startups and (some) "star name" tech companies in those areas hit those figures, but even today I still see more technical jobs than one might imagine in the $80-120K range. I'm aware a lot of software engineers insist that when they're only making $140K they're underpaid given all the Amazing Stupendous Value™ they bring to their companies, but I have some doubts about how sustainable such figures are going to be at most employers as the VC markets tighten (which is definitely happening now).
I don't work at a "star name" company, but it's in the Bay Area. $150k (+/- a few percent) is the typical base for Senior and Lead Engineer positions here. I don't know if that's typical for "not star name" places, though.
And most developers are definitely underpaid relative to the value we provide. From shabby CRUD through deep machine learning research, we're generally underpaid. Partly it's our own collective fault, though: as a group we're told constantly that passion for the product and satisfaction at "being paid [anything] for doing what you love" should be enough, and enough of us buy that crap that it effectively depresses wages.
