Ughhhh what? Again I hate to hate on people who did good in life. You gotta step up your game and find a profession that can earn you above that wage as well as pay off the student loan which if you don't choose the minimal w/the longest time to pay it off, with a ridiculous apr, so you won't be trapped in a financial hole.
But I think that 280k$/yr should be the max anyone can potentially earn and I think you should have to pay 2% more overall in taxes per year on everything city, state and federal once you make over 120k$. For example your excise tax, city water bills and even phone bills would be 2% more.
Not groceries and clothes/general retail. so like credit card bills, Spotify, Netflix wouldn't be more in taxes. Phones are needed in today's society, like you can't do a lot without it. So it would be extra in taxes.
