I appreciate your point of view, but the income left after tax now IS TAXED WHEN YOU SPEND IT beyond the 8% sales tax you see. You just didn't know it because it's hidden in prices. Estimates are that retail prices include 22% federal tax costs.
So you ARE already paying 22% of your after tax money in federal tax when you buy something. The nrst makes the federal tax component visible - it does't raise prices.
It's a replacement tax, not an additional tax.
Show me an example of that.
