You're wrong. The income tax still has people pay tax on medical care - they just have to pay it before they get the medical care. Medical expenses of $100 costs me $128 including taxes [i had 22% effective income tax rate last year.] The nrst simply changes the timing [and lessens the tax a bit] of the tax payment.
I would prefer to keep ALL my earnings and pay tax when I buy something than have my earnings reduced before I even get MY OWN MONEY.
Under the nrst, that $100 medical bill would cost me $118 including taxes [i have a 15% effective nrst rate.]
So under the nrst, I pay less in tax and only pay tax when I spend - not when I invest, gift money, or leave to my children.
All that relates to the Hamilton quote exactly how?
