@Brent cv,
I could go along with a national sales tax . Providing of course that the income tax goes away completely . Suggested percentages are from 17% to 25% of income . That range would be about right IMO , but please don't let them build a Tax office like the IRS !
This might be off Brent's topic , but please educate yourself about the Value Added Tax used in parts of Europe , it is a system we certainly don't want here ! Imagine a tax added on a product at every level of production and distribution . Nightmare in the making . The VAT is extremely cumbersome and just doesn't seem kosher .
