"Share" is the usual word used, not "split."
Rich people shouldn’t split their wealth with the poor. In most countries the wealth pay 90% of the taxes. So they already are sharing it.
You contradict yourself. First you say they should not share their wealth, then you say they already are.
I think you mean "Rich people shouldn't be called on to share even more of their wealth. In most countries, the wealthy already pay 90% of the taxes.
What’s more, they create jobs for people. For example, Guo established the company "Foxcomn," which has six hundred thousand employees. He offers these employees salaries and provides them places to live. He has contributed a lot to society."
