That is so true. There are a lot fewer reports of Chinese being smuggled into the US in freight containers than there were, say, 15 years ago. Mexico could certainly speed things up, though, if they'd get rid of their hide-bound, old-Spanish mentality.
Some of the hardest-working, most traditionalist Americans I know came from Mexico. Controlled immigration is a boon to this country. The problem is having an open 2,000 mile long border with a country so many people want to get out of. It’s too convenient. If Mexico were south of France instead of the USA, they’d have the problem instead of us.
