This, for me, has always been the deal breaker in moving out of VC-funded tech. Leaving corporate tech jobs is already a big enough hit to TC. Getting out of VC-funded tech very often means a dramatic change in life style. The VC world might be insane, but so is the comp.
It's not just the money. The biggest thing I've notice in my career is that, as a general rule, employers value you (or any resource for that matter) in proportion to how much they pay for you. Often people have the illusion that getting paid $80k a year when you used to make $300k will mean that your employer will recognize that you are a tremendous value. They won't. they'll see you and treat you as a low tier worker that can easily be replaced, has timed breaks and 30 minutes for lunch.
