Billionaires don't pay income tax, that's why Dems are raising the corporate tax rate too. They're also looking at increasing estate tax and capital gains tax, and those almost exclusively effect the ultra rich
Some people more likely have an obscene amount of envy to those who are more successful.
I grew up broke and understand how fortunate I am. I'm completely fine with paying a few percent more marginal tax rate. I have thousands of disposable income a month like most of us here. I doubt I would even notice.
Why would you ever think 400k is obscene or crazy amount of money? Companies that those developers work for, earn 10 times as much per developer. I wish every developer could be payed as much or more if possible. Do you find it shameful when other people find value in what developers do and are ready to pay them a lot of money for that value? I'm sure your company will gladly pay you less if you feel overpaid.
