What did he do to obtain that position? Start the company? Can you take the same risks? If you can’t, what sacrifices now would let you take that same risk in a few years? Are those sacrifices worthwhile? If they aren’t worthwhile, then whether he makes 0.9x, 90x, or 900x your income isn’t relevant - you and he have different situations, even if your workloads are similar now. In that case, if you’re happy otherwise, great, stay. If you’re not, leave. Don’t do it because someone with different skills and risk tolerance makes way more - or way less - than you, though.
