I am not sure where you are from but 600k a year is not that much. That's a staff engineer at a well capitalized unicorn. You can reach there within or under a decade. In places like Cali, half of your money goes to taxes. Unless that 600k is in dividends/capital gains, you get diminishing returns the more you make. It's solidly upper middle class, but the elite class ceiling is very high when you have founders making 9 figure exits in low interest rate environments.
(Downvoters can go suck on their sour grapes, if you aren't negotiating a total compensation in line with the value you are creating, that's not my problem. You are in an industry that generates disproportionately large returns per individual contributor and the fact that you don't know how to capture the value of your own labor is entirely on you. Spend less time practicing leetcode and more time on learning business).
