The things you want to do start to expand when you have more money, plus in the first place your budget for mundane shit blows out due to lifestyle inflation. If you socialise with other people in the same income bracket, it's going to happen.
Right, this will naturally happen for most people, but if you're mindful of this effect you can work to curb it if you choose.
There are people in the top 1% who "feel poor" - because they live in expensive homes, drive luxury cars, feel the need to send their kids to the most expensive private schools, and have friends who own yachts - and there are millionaires who basically live like they make $80,000. I would aim more toward the latter (although obviously going too far in that direction can be unhealthy too).
