Do WE create multi-millennia aristocracies? I thought individuals created wealth and chose to pass their already taxed wealth on to their family. I thought estate taxes took already taxed assets from individuals who have passed on.So at the very least you would need estate taxes in addition to sales taxes, unless we want to create multi-millennia aristocracies.
The second issue is that the wealthy spends more of their money off shore, which won't be subject to sales tax.
With regard to the second issue, while some wealthy may spend money off shore, a national sales tax would bring in tax revenue from foreigners who spend money in the US. It would also bring in tax revenue from the income earned through illegal activity and under the table activity.
