How many and who

Talk about the problems at the border often includes the moral obligation to care for those less fortunate but the elephant in the room is mostly overlooked. The big question is, "how many". There are millions of people around the world who are in danger because of social, political and economic reasons. This includes Central America and many countries in South America like Venezuela not to mention many in Africa. Is there a limit to how many the United States can help and if so who decides who gets in and who doesn't.
