wrong, he or she is way off the mark.
I have seen some version of that stadium comment in various ways from Europeans (and even some North Americans), and I am just flabbergasted. It really is another way of saying outside of a precious few venues (e.g., Allianz, Tottenham, Bernabeu, a few others) in Europe, most are just old, decrepit (and small) shitholes. That comment just screams coping about the lack of capital investment in sports and entertainment venues on the continent. For that matter Azteca is a dump (or certainly was before the recent renovation), and that's the case even when the fans are throwing bags of piss on the field. The U.S. could have hosted the entire thing in old, iconic venues - the Rose Bowl, the Cotton Bowl, Ann Arbor, Soldier Field, Lambeau, etc., etc., etc. They chose not to because the fan experience is far superior in a place like Mercedes Benz, Lumen, Jerry World, SoFi, and so forth. If there was one consistent piece of feedback from European fans who actually came and attended games here, it was how impressed they were by the stadiums, especially Mercedes Benz, Lumen, and SoFi. Hell, ask any Notre Dame person who went to the national title game two years ago against OSU in Mercedes about that stadium - it is a genuinely great venue to be in.
The piece about commercialization and ads on the sideline - maybe I just didn't pick up on it, but I watch a fair good bit of EPL and Champions League, and it didn't seem all that different from what you typically see in those leagues.
European fans almost en masse seem to have taken great offense at the hydration breaks. I can see both sides of that argument, and even I was getting annoyed at them, especially in the later rounds. But playing in Miami or even Santa Clara in July is no fricking joke; of the scant few areas in Europe with similar, consistent heat (effectively, the Iberian Peninsula and the central and southern part of Italy) and humidity (almost nowhere in Europe has similar humidity to south Florida or even most of the Southeast U.S.), virtually none of the big leagues are playing meaningful games in the middle of the summer. It will be interesting to see what FIFA does in 2030 - Spain and especially Morocco have climates that could spell trouble for heat casualties. I always like to remind people that Atlanta, GA and Birmingham, AL are on the same latitude as Rabat and Casablanca in Morocco. Philadelphia is about on the same latitude as Madrid.
Similarly, it will be interesting to see what FIFA does for ticket pricing in 2030. Other posters covered it below, but that was definitely not a USSF decision. That was all FIFA. I suspect they will similarly try to maximize revenue as much as possible; the three main hosts, like the three this time around, are major destinations (unlike Qatar and Russia) where a lot of people want to visit. There was something of a hidden demand driver this time around that wasn't there for recent hosts and likely won't be for foreseeable hosts in that the U.S. has a population of 4+ million European ex pats and probably 10+ million Latin American ex pats, living in the U.S. on American salaries, willing to pay those kinds of prices to see their home country play in the World Cup.
