This economy does a lot for the rest of us, it is why you and me aren't fighting in the street for food and why poverty is now defined by proportion of income spent on housing costs and not whether you have a house at all.
If you look at the last 50 years, has poverty, general wellbeing and opportunity gone up or down? All the facts say that we are richer, medically fitter and generally better off than any time before.
The things you are talking about aren't about equalizing society to make it fair, you want to equalize society so it is unfair and punishes the rich.
If you won the lottery, would you distribute your winnings to the local economy or would you keep it for yourself? I know of no-one who would distribute it so why should business owners who took risks and worked hard to pay for that lottery ticket?
Not disagreeing that people are essentially self interested. They'd probably vote for zero taxes despite the fact their lives would tank big time.
This is why we have governments to tax people.
Your idea that people get rich solely due to their own efforts is bogus. They benefit from infrastructure put in place by the state, tax breaks that allow them to get exponentially richer than their staff. A lot is also down to timing and luck.
I am not talking about equalising society as you put it or punishing the rich.
I am talking about an economy that works for the many not the few.
