And it should be that way but some people want to change that because they're selfish. Most billionaires still pay around 1% tax which is way more money than your average person paying 50%. Also it depends on the place but tax heavens like the islands in the Caribbean don't really have public infrastructure ( since ther's no tax) so it's perfectly fair. And if they visit or do business in a high tax country they're still paying sales tax or inderectly contributing to income tax through creating more/better job opportunities
