Certainly.
This really comes from a line of thought that when you look at income taxes versus consumption taxes, consumption taxes are good taxes and income taxes are bad taxes. I'd have to be a theoretical tax person to explain that better to you. I'm only repeating the published tax efficiency of both those types of taxes.
I said we question it, but we don't know. The party line--not any of the parties here--in tax theory is that consumption taxes are the way to go, and income taxes are not, if you're trying to raise revenue.
