The solution to assist mass deportation is to get them to progressively deport themselves. Give them some reward to leave voluntarily, and make the consequences for not leaving progressively worse, and worse, and WORSE. Possibly do it in cooperation with Mexico, so for example the longer stay and resist deportation, the more severe your punishment is going to be IN MEXICO (for example)... fines, imprisonment, etc. We have to stop rewarding them for bad behavior and start punishing them for it. Simple. In theory it is so very simple. The problem is corruption.
