Exactly, I think since we had an economic crisis in most of the countries and they don't have good situations it was a wise move to let a country like America host the world cup because they have enough potential to host the great events and even if Mexico and Canada were not co-hosting the world cup America could easily host the world cup by itself.
I doubt that this has anything to do with the economic crisis or with the pandemic as the bid to become the World Cup host was made in 2017. I think that the USA along with Mexico and Canada had the strongest application in the field. I don't know whether this trend that there will be joint co-hosting will continue in the future, but I am still an advocate of this decision. There are so many countries in the world and if you want to give most of them a fair chance to host a World Cup anytime soon, allowing for co-hosting makes a lot of sense.
