Do most people not understand what tariffs are?

When Trump puts 25% tariffs on certain Canadian goods, Americans that buy those goods have to now pay an additional 25% to the US Government. Canadians are only 'punished' in the sense that Americans are now slightly less likely to buy their products. Opposite for the retaliatory tariffs.

The American tariffs seem an awful lot like an easy way to tax the American people without calling it a tax.
