But you're forgetting, Mexico is about as corrupt a country as they come. Even law enforcement down there can be bribed with protitutes, and little cash. That alone makes this desirable.
But you forget, too, that Canada has the same demographic problem we have, but without the booming economy. In their last election (last month) one of their platforms was recruiting immigrants and training them in technical skills. If they have the technical skill, they get little resistence to citizenship.
That means they won't be followed, they won't be hiding, and they won't be watched.
That scares me more.
