Do you really think that the government just confiscate their withholdings?
I explained to you they already have. Taxes are confiscated. They're not a deposit you can elect to draw upon. These aren't novel concepts, and I've already familiarized with the Supreme Court's ruling specific to this fact.
Is English your first language?
confiscation
känfəˈskāSHən
Confiscation is the permanent, involuntary taking of private property by a government or authorized public entity, typically as a penalty, without compensation to the owner.

Exactly what you are proposing except the penalty is for being wealthy.
