I disagree. In Russia an average employed person never even has to file income tax declaration, and any local sales taxes are included in the final price. People don't even know how much they're taxed. All they know is that income tax is 13%, they don't realize how many other taxes are added up to both their salary and the products they buy.

As much as the mental overhead of expecting a sales tax on checkout annoys me, I'll suffer through it so that everyone has a constant reminder that the government is taking its cut.
