Nobody is going to pay me $500K. Nobody is going to pay me $200K. As recently as 2015, I still had well-known companies trying as hard as they could to bring me on at under $100K! The last time I talked to an SV company publicly claiming to offer $250K, it turned out they were reserving the "top end" for imaginary devs. My work experience only weighed in at $150, according to them. Also, despite having a very rare combination of two unrelated specialties (the reason I applied), and being proficient in 6 languages, including JS, they passed because they felt my JS experience was too light. Writing the AJAX and UI framework used by a team of 30, and working on the front end of a major portal, both at BigCo, were apparently too small-time.
My whole career in the industry I was aggressively low-balled 9 times out of 10. Hiring people can't hire who they want, because they're scheming double-talkers, and they've convinced themselves that it's just good business. I started a small business that pays the bills, and I've never been happier. I sincerely would not go back to the industry even if you did pay me $500K.
