I don't know what's the reason behind why Qatar wanted to host World Cup because it's probably not the money they are after because they are already petrol nation which economic doesn't need some more boost as with or without World Cup, their nation is already rich enough. And I doubt if they after the tourist because from my perspective, they aren't much of a tourist friendly nation.
I visited this country just once a few years ago and I can say Qatar is just a rich friendly country, if you have enough money you can enjoy in this country and do anything you want while for normal people it won't be a good experience while comparing to America here we are going to see the next world cup on it you have luxury hotels and mostly I see rich people visit this country, but in America even if you don't have enough money you have your stay in that country which can be good for the people who go America for the world cup.
Nothing surprising though, America and Qatar should never be the same, and I am happy they are not, America is the world power, and as such, it is just morally normal that it should be able to accommodate visitors from other parts of the world, no matter what their financial capacity is like.
If all things were to be normal, America, to me, is supposed to be one of the easiest countries to travel to, since it is a country several other countries look up to, but it's rather unfortunate that, the revise is the case if we begin to compare.
on the other hand - Qatar is easiest to travel and they an amazing work in hosting the world cup - there is no doubt about it
