in other words, the proposed is a policy for which other people (whom you view as having more wealth) gets taxed for a benefit for which you will gain.
In my country I am taxed 52%, and I don't mind that. I clearly see the money going into public infrastructure, roads, public transport, social housing, greening the cities, etc. If I am unable to work due to illness, I will benefit from 80% of my salary for many years, and after that, 70%. You should give more to the system proportionately to how wealthy you are. People with 10 mansions and a fleet of cars and a private jet while there are homeless on the streets, that is an abberation. The current system is failing because when people get beyond a certain amount of wealth, their wealth can increase exponentially, while they are not taxed exponentially. It's a finite planet, after all. Infinite wealth growth of a few while many can barely afford rent is like cancer and should be taxed to oblivion.
If I was earning more, I would not mind sharing an ever increasing percentage of that in terms of taxes. I don't need 20 houses and 20 cars, and my own rocket, no individual person needs that. People like that should not be allowed to exist by the government.
