I earn a lot less than the amount you suggest in your OP. But my mandatory outgoings are small, and thankfully my tastes aren't crazy expensive. That means overall I don't ever have to worry about money: I know I save enough for my pension; I overpay my mortgage; I have enough cash savings to replace my car, boiler, keep me going if I was made redundant; and I have basically all the luxuries I could want (cleaner, gym membership, good food, decent wine, holidays). But it's not like I could just go and buy a Porsche outright, or go on crazy trips every year - feeling those things would destroy my financial stability - but as I have no desire to be that rich really it doesn't cause me to worry about money. I could upgrade my house, run a fancy car, go on bigger holidays. But that's lifestyle inflation and would be a great way to have to worry about money again.
We didn't have money when I was little - and I think that always sticks with you. I still take months deciding if it's "worth" buying things, even practical things. It's completely absurd because I could afford all of them. I think I have a real desire not to end up with too much lifestyle inflation: I already have a cleaner and a fancy gym membership, and I watch my friend wasting money hand over fist and it just makes me feel sick.
That's not to say I don't have nice things: I have lovely coats, nice boots, good bed linen etc. But those things last years and I still remember the surges. I bought 3 bath towels, it would have been 5.5 years ago now, in June or July and they cost £72 in total. They're still going very nicely.
One of things I have had to try really hard to do now I have more money is stop the guilt when things don't go right - losing a set of headphones, breaking some crockery, staining something. I do still feels guilty but it doesn't wake me up at night anymore.
