And why should it be a problem if there is wealth inequality? When you have a company and make a lot of money you don't steal from anyone. All money that you earn is coming from customers that freely give up their hard earned money in exchange for whatever you are selling. The only one who is stealing your money is the government, actually you are robbed because they will use force if you don't hand over your property.
Also why should rich people pay more taxes than poor people? What is the moral reasoning behind that? As I see it you pay for government services and to me it is immoral that one has to overpay 100x for a service while someone else pays a fraction of that. It's as if you walk into a coffee shop and one guy pays $1 for a cup of coffee while another rich person is forced to pay $100 for the same cup of coffee.
No wonder that rich people move their money somewhere else. If a majority survives by leeching off a productive minority then eventually the system will fail and people will live in abject misery and poverty.
