This isn't true: local (to me) jurisdictions vary between an 8ish% sales tax and a 10% sales tax. In many states, there's no sales tax on food but food is taxed in Alabama. There's any number of variations of this in the US.

Both of those sentences are completely incorrect.

> VAT rate differ based on the origin which is the issue

Which is a lie. They do not differ based on the origin and that is not the issue.

The issue is that American top politicians are used and enabled to brazenly lie and their voters spread it happily.

In what way does VAT differ based on the origin? All VAT is cancelled out except for the final purchase by a consumer, no?

WTF? No. Not even remotely true. Rates vary by state and locality. And vary across type of good being sold. You couldn’t be more wrong if you tried.
