The money made from the drug cartels, gangs, coyotes, child slavery the kick backs to the governments, law enforcement. Not to mention tax free money sent home from the illegals in the US. This is their current economy structure and they have become dependent on the money and our open boarders to support their economies. With the boarders closed and the money drying up they have no idea how they are going to support their countries they have become dependent on US money. They have no idea how they will survive with out it. They don't want these criminals back in their country. They should of cleaned up this mess years ago and broken up these gangs and criminals that are terrorizing their countries. I am sure our government and military would of helped them clean it up if they had asked. They have created the countries they are going to have to live in.
