trust me the world will not collapse with a National Sales Tax - Canada introduced it in 1990.......we're doing fine.....but I believe you must cut income taxes at the same time you introduce the tax.......
in Ontario we pay 8 per cent provincial sales tax on all goods, then the 7 per cent GST on most goods and services for a total of 15 per cent
many European VAT taxes are much higher than 15 per cent and they have high income tax rates.......which I wouldn't recommend.......
.....but I believe you must cut income taxes at the same time you introduce the tax......
.The Bill being proposed eliminates the federal income tax and the IRS. That's way more than cutting.
