As far as I know, only the FairTaxers believe government can raise revenue by taxing itself.
As i said previously, it really would be nice if you folks could, or would, actually READ the paper under discussion.
The following quoted directly from that paper:
"2.2 Government Consumption Spending
Government consumption is included in the FairTax base in order to put personal and government consumption expenditures on an equal footing."
I cannot help it that you, and a few others here, cannot grasp the great importance of doing that but most folks do so quite readily.
