Moving to SF/NY makes sense if you're an ambitious, hard-working extrovert who knows how to sell and take advantage of those networks. For ambitious introverts like myself, remote consulting/contracting feels like the best option. A childhood buddy of mine moved to SF last year and got a job at a big corp downtown. He manages to save around $3,000/month as a senior developer with a ~$200k salary. No children, living with a partner who works as a teacher, and they're both quite frugal. I work as a remote contractor from a small European town and am able to consistently save way more than that. I was saving more than that even in the past while working as a sub-contractor through platforms like Toptal. How big of a salary would one need in order to save > $100k/year in SF (Single, small rental apartment, no car, average middle-class lifestyle)?
