Privilege for the disabled

I just learned that in some countries disabled people's welfare are quite well looked after compared to what we have in ours. I think it's thoughtful and good that special people like these are helped along the way.

I guess it does make sense for special people to want to migrate to those countries where there is disability appeal for them. But I wonder if such applications are easily acceptable?

I know nothing in this area. Don't mind my midnight rambles.
