America and Mexico can prepare for the tournament in their own country all these years. That seems to me to be a huge advantage compared to other countries that have a hard time qualifying for this tournament. In principle, Mexico and America could also qualify themselves, but it could also go wrong. Canada may not even have qualified otherwise, but they managed to qualify at the previous World Cup by the way. It seems that America has big plans and wants to invest a lot of money in American football, which is certainly not one of the first 3 national sports.
