One of the best explanations of why large-scale immigration doesn't work. Now, I've said this before... but if you do make your way here (legally or... a border crossing or ... a raft from Cuba), I'm on your side if you're willing to bust your ass. That said, it doesn't make sense for any country (America or otherwise) to support a mass exodus. It's only going to strain resources and infrastructure. The answer is to help people where they live. Again, being global citizens. We need to help one another.
Just some musings from an old guy...
