Well, I can't speak to SF. I can tell you that in NYC, these salaries are going down down down as the supply of "junior Rails semi-devs" (hilarious btw) climbs ever higher with the rise of the last viable profitable education gambit: the bootcamp. I've actually started to see full time SWE positions on AngelList for $40,000 per year. (I know!!!!!) I realize you guys aren't a bootcamp, and I'm not speaking to anyone in particular here. Although- how are you not a bootcamp? Because by bootcamp, I loosely mean: a non-degree granting thing that gives you some skills you can sell in the decaying labor marketplace, but quickly, before it totally decays and there is nothing left at all. Anyhow, labor is dead. We all know it. Here is a great little piece from The Baffler on this point. https://thebaffler.com/salvos/why-work-livingston

That said, it is tough to do the actual life of a 2017 Bourgeois Professional with the income of a manual laborer (debt slave), even for a few years, because the theater of this requires a lot of energy, perfect physical health, and a great wardrobe to start, not to mention the attitudes and social mores that take a lifetime to learn. No one speaks of this crushing emotional toll that adds up to very real financial expenditures that help one deal with these theatrical maneuvers over time. It comes at great financial and psychological cost. People wonder why there is so much burnout in this field... I'm not claiming you should take this on. Not at all. It's just that it is never talked about. Some of these these "bootcamps" are desperate... some of these are in the top tier in SF and NYC. It seems that these issues should be raised at some point and discussed in a place like this one is all I'm saying.
