In my experience, most engineers, even those fresh out of college, land at above 300k within a few years at Google/FB. You do not need to be a rockstar, and you don't need to work more than 40 hours/week for that (though that can depend on team, I've never encountered one that regularly asks for more than that).

If you're talking finances, Google/Facebook will pay you more, with less risk, and better work life balance than pretty much all startups. There are entirely justifiable reasons to prefer a startup, but you should take a second look at your calculations if you think finances come out favorable on the startup side.
