I am in favor of a FLAT tax from an economic perspective. No doubt your plan would be a tremendous economic stimulus. However, from a liberty perspective I have to go with the FAIR tax. See my post #44 second paragraph for one reason why we should repeal the 16th amendment and have a FAIR tax.
The FAIR tax is entirely too complicated, especially if it includes the horrendous “prebate” and too open to fiddling. Normally the percentage is fixed way too high by proponents because they want it to be”revenue neutral” and supersede all general taxes including state levies which would further erode the sovereignty of the States. It appears to be a centralist scheme.
