What you describe is pretty much true for every single american sport too

>unprecedented levels of gambling

Welcome to FanDuel and DraftKings

>insane amount of efforts from the youth chasing the dream of professional football

Look at college sports, it's actually even more insane than anything else in Europe

>corruption where magnate owners of sports clubs use their popularity to influence politics

Look at how public money spent by universities on sports (especially in the South) or how pro teams' funded by local taxes. And when the rich doesn't get a deal they just move the team away. The Minneapolis Lakers moved to Los Angeles where there are no lakes. The Oilers moved to Tennessee where there is no oil. The Jazz moved to Salt Lake City where they don't allow music.

>fan violence inside and outside the stadiums

This is the only thing you might be right about it... but hey it's US, land of the free guns you don't need fan violence for that
