This is an interesting question. When you say what % should they pay, do you mean as a whole, or as per their income levels? Because as a whole, it is commense sense they would be paying the majority of the taxes since they have such greater income levels.
I think realistically they should pay 75% or more of the total taxes.
What they are claimed to have to pay and what they actually pay thanks to loop wholes is an entirely different thing, though.
