What a boneheaded reply. Don't be a fuckwit. Cut the ableism, lack of awareness, personal privilege, and national differences. What are people with disabilities supposed to do? People who don't or can't drive? People talking care of their infirmed family? People without the thousands of dollars needed to enter a country and live there without a job until they find one that will sponsor them?
According to you, they should take the risk on being sent back to the US poorer than when they started, end up homeless in a strange place, and/or let their family members die alone without support.
I say this as a US citizen trying to get out and having done a TON of digging into what it takes to leave here specifically and go to a European country. There's more involved than you seem to know. And a boatload of risks.
Not everyone lives where and how you do.
