This seems to be a problem with not having uniform policies across the nation. I think a similar thing is happening in the European Union with its free movement but no uniform internal policies -- locations that have more generous policies attract needy from the places that don't. I'm all for universal health coverage and making sure that people who can't find work can get support, but this is why piecemeal solutions don't work. It needs to be national.
