And don't forget the next World Cup will hosted by three separate countries, so expect that there will some games that will be played simultaneously.
Yes, it's not hard to do more games simultaneously, USA alone is a huge country, with great infrastructure to travel, Canada and Mexico will host only 10 matches each one, but it will help, so it's not a impossible task.
There will be approximately 100 matches for the 2026 edition, which is relatively higher than what we had during Qatar 2022 (64 matches in 28 days). But then, some of the leagues around the world have even more matches and no one complains about them. The English Premier League has close to 200 matches per season and no one argues that it is too long. World Cup happens once every 4 years and the fans deserve a tournament that lasts at least 1 month.
As I said above, I think it's not hard to do these 100 matches in 3 countries, specially with USA being the main host.
Maybe it could be a problem in the next editions if they choose smaller countries. But as everything indicates, the 2030 cup will also be in at least 3 countries, and the trend is that it will be like this in the future. Probably no more World Cup in just one country.
I couldn't find any long term improvement for the United States, that came from the 1994 World Cup. Huge amounts of funds have been spent in popularizing football in that country, but the Major League Soccer (MLS) lags other sports such as NBA, NHL, NFL and MLB in terms of popularity and participation. Now awarding them the 2026 world cup is another attempt to popularize football within that country. What makes them think that the same strategy, that didn't worked well in 1994 will work this time around?
In my opinion there's a lot of improvement after 1994
1954 to 1986 they did not qualify for World Cup, but after that they only missed 2018 in Russia
I remember in 2002 they got to quarters, and lost to Germany, probably the best USA team I saw.
Unfortunately there was a handball that saved Germany, and in my opinion it was a HUGE mistake against USA, they would get to semi finals
Take a look:

You also have to consider that MLS is always trying to attract good players and having more audience, but it is very hard to compete with Europe.
