Can you be specific about the problems we have already stemming from Mexican immigration and how an EU-type open border with Mexico would exacerbate them?

And yeah, passports are now required for Canada and vice versa, which was a dumb, neo-conservative reaction established after 9/11. We should end that yesterday.

The kind of open borders the EU has is exactly what I'm interested in. North America should do the same thing.

There are plenty of jobs here to support it. And plenty of room. We have a housing price crunch now but that could be alleviated with better housing policy and home ownership rules regarding investors.

Don't fret. None of this is happening. Not this year, not in five years, probably not in 20.
