Yeah, and for a really capitalistic reason: you can compare a night at the restaurant with a night at the movie to allocate your budget, wheras in the US you have to know the tax on movie tickets, the tax on food (good luck, theses are defined by town), and the tip you will leave.

Capitalism only work if both side of the transaction have the same information, that's how Stiglitz got his Nobel prize. (another US trope: collecting the Nobel prizes and never reading the papers)
