Why Aren’t The Insane Gossipers Self Deport?

I have wondered why haven’t the mass insane gossipers, who are remaining in America don’t self deport themselves into Mexico? At least two million residents who lived in America, self deported themselves within just one year! The mass insane gossipers chances of a longer physical existence may be longer, if they self deport themselves, perhaps, those insane gossipers don’t like their current existence! If, so, wouldn’t they be out from the USA!?
