Let's stop some of the foolishness.
Yes people live in the bay, SF even making 60-70k and do fine. i don't know where someone got $5-7k for s one bedroom
These startup and tech jobs aren't all fun and games, yes there is a laidback atmosphere but some dude was posting shyt like people are putting in 40 and chilling...no, most coders are putting in way more hours which is the reason these tech companies have so many perks.
I'm not privy to all facets of dev and the whole cert gang, but y'all who don't have 4 year degrees and/or think you'll do a bootcamp with some AA degree and think you'll get a job at the types of companies listed in OP are WAY off base. Now how that translates elsewhere or into other roles outside SV, I can't speak on...but getting on at Google Twitter Facebook or the sexiest startups/unicorns...you need the name brand college killer skills and ability to sell yourself on "fit".
