So according to the author of the article and the best definition you've seen as "wealthy" "most saving and investment are done by the wealthy"...BS! How many people/investors fall into that category?
Just because most of us will never accomplish that level of equilibrium doesn't mean we aren't saving money.
I fully agree with the concern that the NRST could be corrupted into a very targeted exercise in social engineering. We already see evidence of that with cigarette taxes being the most egregious. Don Perata was targeting gun owners with a proposed 5 cents per round tax in California. The environmentalists stuck us with CRV tax on soft drink cans and bottles in California. There is no end the the possibilities. Consider the nightmare of keeping millions of merchants updated on their current tax collection duties.
