"It doesn't spread in European schools" doesn't really help us very much in evaluating what'll happen in America right now.

It's like we're the kid in school who refused to do their work, then has a tempter-tantrum because they have to forgo recess. And much of the EU (and Taiwan, Singapore, HK, etc) are the nerdy kid who finished early and now get to spend the afternoon doing something fun.
