I'm not sure, I can't imagine feeling that way. The jump from $500k to $650k, or 1mil to 1.2mil, would still feel pretty significant, in terms of cash hitting your bank account.
Honestly, many many people feel that way. I have been there most of my working life.
When you don’t make enough to make ends meet, or to do so comfortably, sure, fixing that situation is going to be very important to you.
But once you have what you need to live the life you want, why not simply live the life you want? One of my closest friends has been at google for almost 20 years. He doesn’t want to be promoted because he likes his job and his coworkers.
I don't think this is correct. I'm lucky enough to be on a level where turning down a 100k increase in salary is something that I have to routinely do because my current job ticks so many boxes and I genuinely love it and don't have to risk it for that amount.
I'm not saying these people wouldn't take a six figure pay cut for a job they like better. Just saying a six figure increase can still be pretty significant and material.
