I don't know. If I were self employed, and you buy a thing from me, is that your consumption (taxed) or my income (untaxed)? This stuff is complicated.

... thinking about it further: A truly crazy idea would be a consumption tax that is based on the income of the seller, to keep it from being regressive. Things from rich people are more expensive as a result, providing a nice anti-monopoly, anti-inequality balance. Now I want everyone to poke holes in why it would fall apart.

My thought is that this would be problematic in markets with natural monopolies. There aren't a lot of mom-and-pop power companies. (There are plenty of moms and pops selling power, but as I understand they sell it to the power company who resells it to you by burning less coal.)
