If we (the US) could bring them here and basically dump them with introductions to the churches in the dump area, and refuse them any Federal and State aid until citizenship, and make citizenship a difficult but eminently doable project taking 5 years at least, then we would be gaining new hardworking and increasingly productive citizens. They would eventually be valuable additions even as we insist that they become welfare burdens. They will come out of it but it will take longer. I watched it happen to the Vietnamese nguoi Kinh in my hometown. The nonCatholics were sucked into all manner of welfare schemes against their will ( they came very suspicious of government intentions of any kind) by threats to deport them. The Catholics called the priest who called the bishop who told them to tell the welfare people to get off their doorsteps or the sheriff would be called- and then call that sheriff.
The Buddhists are in the projects hiding income just as the welfare people have traiined them to do while the Catholics are rapidly becoming prosperous as the owners of many small businesses that they have started or acquired by their own efforts. The Hmong and other mountain people from "Indochina" will all work hard and will rise if the government leaves them to it. And they will pay the social security taxes that might keep the system solvent a little longer and maybe there will be some left for my own retirement.
