The NRST is an inherently regressive form of taxation that is truly despotic.
Regressive means that they must spend a larger proportion of their resources simply to acquire necessities: food, clothing, shelter, medicines. Therefor, placing a tax on these items is much more burdensome to lower incomes citizens than it is to those who are more affluent and have greater discretion and choice over the utilization of their resources.
Doesn't have anything to do with how much you buy. Its what percentage of your income you're taxed on.
