Since corporations are people, why shouldn’t they pay taxes, or did I misinterpret your message?
Corporations are not people, Soylent Green is.
Anyway, if you charge corporations taxes, the consumer pays the increase in the form of higher prices. That increase is paid with money that has already been taxed in the form of income. That is called inflation. The particularly odious kind of inflation, that leads to hyper-inflation.
Corporate taxes are nothing more than the government outsourcing extra taxes and forcing corporations to spend the money collecting them.
If an entity can’t vote, then it should not be taxed.
