I think you mean, convince politicians to allow for the ridiculous tax-excluded display pricing that’s prolific in the US.
Perhaps what's ridiculous is that we have so many different taxing jurisdictions.
So I’d rather have to do some basic math but save 10% (of course different tax rates only partially explain the price difference, it still is significantly more expensive in Europe without VAT)
Why is that ridiculous? I don't pay sales tax, what else would you have them advertise?
