Let's see...
Take a group of young, income earning, income tax paying individuals --
many of whom are earning/have earned college degrees...
all of which are actively participating in the economy ...
and are contributing members of the workforce whose employers have invested time & money into their training...
and evict them from their homes, fire them from their jobs, and send them to a country that many of them have no memory of ... nor any ties to...
just because you can?

Yeah.. that's excellent "business" sense..
Not to mention that
Even Genghis Khan treated his subjects with more compassion...
