They will.
I agree with you re: the grassroots and academy structure: it is dreadful and pay-to-play. However, we have a population 10x many of the best footballing countries. Soccer’s popularity in the country is increasing. We have a larger genetic pool to pick top talent from. We have a culture of “i need to be the best” that overshadows many others. I’m not saying its’ going to be this or the next WC. All I’m saying is if you want to bet on a non-Europe or South American nation to win, it will be the US.
I’m not even a fan of the US team, I support Scotland. But we (for better or worse) will win the WC simply due to athelticism and a larger population to pull talent from than many other countries, if nothing else.
EDIT: Oh and the US has already made it to the Semifinals, although their best RECENT result was the Quarters, which in itself is already better than 85% (my made up percentage to just highlight my point) of other nations vying for the WC.
As a fan, I don’t think there are too many matches. It’s kind of like being a manual laborer and complaining that working HARD 35 days per year is too much because of the other 150 days of light (ie practice) work you do on top of that.
At least footballers get paid an amount of money to make the effort worth it.
