Tell me something: Did the NRST proposal spring fully-formed, in every legislative detail, from someone's head like Athena from Zeus, or was it the result of people talking about different ideas to see what would work and what wouldn't?
It came from a group of small businessmen in Texas who put in the necessary bucks and effort to create a proposal for a tax system developed on a basis of economic studies, basic constitutional law, and a firm grounding in the proper legislative language to achieve the goal of eliminating the income/payroll tax system completely.
The first draft was not offered to the general public, or Congress for that matter, until proposed legislative language was written and offered to be introduced in Congress where the debate could begin on the basis of the solid foundation rooted in the studies and legal work performed in its development.
Too many fingers in the pot at the front end is guaranteed to spoil the pie and miss the goal for lack of focus.
The heavy lifting been done, the bill and background on which it stands is out before the public in open view for debate, criticism, and refinement. Go to it.
