No offense but that is a really ignorant question. If my earnings are tax free I can invest, pay off personal debt, gamble do what ever tax free. Most of all I can save tax free in an account that is not controlled by Uncle Sam. Do you see the difference now? It's called freedom.
Now if you are retired you are probably against it, but the economic war and the youth of America needs to stop.
Plus tariffs promote domestic industry and job growth.
First, all questions are ignorant that's why they are asked. (Unless it's a rhetorical question.) Second, your argument relies on several assumptions that are not part of the original discussion. You assume that the sales tax law will allow you to do all of the things that you say, but until the provisions of the law actually exist. We don't know if you can do any of the things that you claim. You also won't get any tax break or write-offs so your sales tax could be worse than the current system. Less write-offs could result in less money for the taxpayer and thus less freedom. Your sales tax is only a better thing than your theoretical sales tax if your assumptions about it are true.
Secondly, a National Sales Tax may be unconstitutional, since it is a direct tax not based on the enumeration of the census. The 16th amendment arguably only allows the income tax to be levied without having to be based on the enumeration of the census.
By the way, I just wanted to say thanks for the perspective. It was very informative. That's why I asked the question.
