Actually, the poor will be taxed more heavily because in the US at least, they pay no income taxes now at all. So any user fee or tax would hit them at whatever the rate would be and most say that rate would need to be a minimum of 15% to 20%. That would be on every dollar they spend. It is actually a more equitable tax because now the top 5% of taxpayers pay 90% of the taxes.
I'm all for it, but you know as well as I that it wouldn't last long. The rate would only go up or there would be other ways for the government to get into our pockets
