By the way, I understand the anxiety with the visuals of these many people heading to the US boarder, but if you think about it carefully, you will realise that a lot of it is overblown and politicised. The drama of people in a caravan across several countries heading to the US adds to the frenzy, and it doesn't help that the president is threatening to send the army to meet civilians.
5,000 isn't really that many people. There are more than that coming in casually via the airports every day. Many of them are would be illegals. I have many friends from Europe that travelled to the US on a tourist visa and simply never came back. They are illegal, but nobody bothers them. If they were caught, then probably the'd be deported, but they seem to be fine for now. They work (taking away work that would otherwise be taken by Americans), and benefit from the resources of the country. Where's the outrage? You see what I mean?
