If you can't hold something down for more than a year then it looks rough to anybody.

18-24 months generally seems to have been the sweet spot in terms of improving your income. Especially because the promise of equity after 4 years often means fuck all and you almost never see a promotion or a decent pay increase either for inflation or performance.

If an employer is going to ding you for taking advantage of the market then they better be offering enough above market to keep you around for longer.

I'll agree that switching jobs is often good for income. But I think it's a fallacy to say that you "improved" more by doing it vs if you hadn't (obviously depends on the situation). It's a breadth vs depth thing. You are sacrificing depth for breadth. Not a bad thing at all. But if you write code, left it behind, and don't get to see what happens to it, then you're cutting off your own feedback loop.
