Can someone tell me why ILLEGAL immigrants SHOULDN'T be removed?

well, if you are a human being who cares about the welfare of others, consider that there are about ten million undocumented people in the US.. most of them work hard, have families,, and have lived here for many years,, forcing them to go home would cause a huge humanitarian crisis, harm families,, hurt our own economy since we rely on their labor , would cause prices to sky rocket, not to mention would be absolutely terrible for children who have grown up here and don't speak spanish or know any other culture.. it would be cruel and would be the same as shooting ourselves in the foot.
