Ahem. If the government taxing itself generates revenue
The federal government taxes the income of its judges. it also pays those taxes that are embedded in the price of consumption goods and services. SS recipients pay federal taxes out of SS money, federal employees and military pay federal taxes from federal dollars as well.
Treasury doesn't care about the route money takes to get to it's coffers.
the tax laws were for exempting all state sales tax
NRST is a federal tax lewislynn, not a "state" tax. Nothing in the Constitution prevents a government(state or federal) from levying a tax on itself.
So in your mind those are definitions of the government taxing itself?
What are "federal dollars" exactly?
