Taxing the rich/wealthy never ends there.
It always drifts down to lower income investors.
If the people who run the country can lower their own taxes and then spend what they want to what do you think will happen? Who do you think will pay for it? Making these people pay the taxes when they are spending the money is the way to correct this disparity. Actually the threat of higher taxes may be what it takes to change their minds. And then we don’t have to raise them in reality.
Threatening to tax the people who spend the money is the only way to keep massive deficits from happening. We have huge deficits that have happened as we have lowered upper class taxes. Since they do not have to pay so much in taxes they don’t care about regning in spending especially when they control the spending and it goes to their concerns.
