I'm American, so I'm not sure who your comment is for. Anti-Americanism isn't a "gotcha" to me. If anything, it's confirmation of the persistent asymmetry in these discussions.

Football (or basketball, if you're Lithuanian) is a massive cultural institution in many parts of the world. The difference is that sports—just sports—are the institution in America. We could look at revenues, but that's far too easy. Look at the whole picture. Look at youth participation, women's sports, college sports. It's not comparable anywhere else.

For football specifically, the current situation is that a handful of European countries control the best leagues and consistently have the best international squads. This isn't changing anytime soon. The game is already owned by a group of elite countries—almost exclusively in Europe, benefitting from geography, mutual competition, and visa gatekeeping—and one confederation (UEFA).

The fact that the game shouldn't be "ruined" (or latent anti-Americanism) suggests you're okay with this situation. You didn't comment on rule enforcement or cynical play either, but I assume you're okay with those things or take them for granted.

Americans see football through the lens of other sports, because we are a sporting culture, and football is one of many. All the "American" sports have their problems too, but we don't pretend they don't for phony reasons. But we also have choices and exercise those choices. Footballing nations, I get the impression, see all sports through the lens of football. I often wonder whether fans in footballing countries genuinely like their sport for what it is or whether it's just a narcissistic cultural inheritance.
