3 month bootcamp attendees shouldn't make more than $75k. They are junior as hell, and add little if not negative value for a long stretch of time. Even $75k is a reflection of the crazy job market, not their actual value.
Your COL & salary analysis for SF is incredibly off. Yeah you'll probably have to sacrifice the excesses of your upper middle class SF lifestyle (boo hoo...). You can easily live on $75/k year in a $1600/mo studio in the Tenderloin, or on the flip side you can have a $1600/mo shared apartment in the Marina. You can't do that if you have a family, (but if you do, that's on you for switching to programming while needing to support a family).
Crappy programmer entitlement is just so off the charts (and disjointed from reality) it's a little frustrating.
