To be honest I doubt any country is better than the other as generally we live in a money driven capitalistic world and little or no resources are provided for spaces where people can get together. In the Uk where I'm from we had absolutely no support at all this is going back 20 yrs though. Wouldn't it be a wonderful world if there was venues available for people to go to ..to jus be able to get together having socialisation with others with asd. I'm wondering about this as my son says he avoids neuro typical people who are out and about but would feel better going to a place where there are people with asd like him. I've seen a lot if documentary about these things but it mainly seems to happen in Australia
Maybe it happen in that country due to the weather ie they are more going out and not stuck in doors on a computer Idk.However even if you found a country that could provide a better quality of life for you that your current country can't do, I found out that I think nearly all countries now do not allow you to become a citizen if you have an asd diagnosis...but that's a whole other thing .
