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.
I think when you can do whatever you want as a tourist with money whereas the regular common people can't, that doesn't feel like a country I would love to visit.
This isn't anything regarding religion or anything, by same logic I never want to visit Thailand and you can "do" many things there that you can't do in Qatar, I mean as free as it gets and it's cheap and it allows people to do so many things, so as you can see there is a huge difference in that regard, religiously I mean, and culturally, they literally have fame about being able to "do" anything. And yet I wouldn't want to visit. Because when rich tourists are capable of doing all those things and living a great life there, common people can't, and I am against that.
