Really if we and Australia are “trading people” isn’t that human trafficking basically a form of slavery?
No, not legally, because it is entirely voluntary on their part. In both cases, they are completely free to stay where they are. In Australia’s case, if they refuse this deal, we’d have to continue to try to find them somewhere else to go. I’m not sure what the circumstances are for the US side of things, but it is voluntary to ensure it can’t be construed as human trafficking or slavery.
