"here in united states it is 7.25% for the highest tax state, california."
I'm sorry, you need to do better research.
1 Tennessee 9.35%
2 Louisiana 8.70%
3 Washington 8.45%
4 New York 8.25%
5 Oklahoma 8.15%
6 Alabama 8.00%
7 Arkansas 8.00%
8 California 7.95%
9 Texas 7.95%
10 Arizona 7.80%
And realistically, most of those are higher. I live in Arizona, and I typically pay more than 8% thanks to city/county tax.

Anyway, VAT works in a totally different way than sales tax, so it's pointless to compare them directly.
And on top of that, there is a difference in the buying power of a Dollar and a Euro. While conversion rates highly favor the Euro, meaning it's good for Europeans to travel to the U.S., basic costs of living are still practically 1 to 1 in most places.
You do not have the right to never be offended.
