This is very funny to me because I can't still understand what you mean that Quatar killed a lot for workers just to build a shiny stadium. Many of the countries that had been hosting the world cup always build a stadium for it because they know that it will bring center if attraction to them and make people that likes to go on vacation to see good reasons of coming to there country for flexing and holiday. Since the United States and Canada would be hosting the world cup, I hope to see impressive stadium and enough space for people to enjoy themselves.
Well, the US and Mexico already have hosted the world cup in the past, so I guess the pressure of new stadiums would be mostly for Canada.
Even though there will be only a few matches in Canada and Mexico, most of the matches are going to be in the US, which already have a reasonable amount of stadiums.
I don't think there will be many new stadiums built for that world cup.
I don't know about that but just like what you have said, only few games will be played in both Canada and Mexico so they might stick to what they have instead of building stadiums that will probably waste them more money instead of benefitting from the event, but maybe there will be some few changes in their existing stadiums like increasing the capacities if they can and make it more luxurious as not every time they can host such event.
