That's exactly right. The reason Vicente Fox and his cohorts are pushing their guest worker plan is that they very much fear being overthrown --- not just a political party but the entire corrupt Mexican government will be overthrown without 2 million Mexicans leaving every year.
There is no more hope in Mexico. For the time being our leaders in the USA are allowing the Mexican leaders to dictate the terms of our immigration policies to help them stay in power as long as possible because as bad as they are they are seen as some kind of stability.
But the massive exodus of people out is actually making everything worse in Mexico.
I see the workers exodus [and their money sent home] as a safety valve, but essentially, we agree.
-- Mexico is ripe for revolution, and our government is playing games at our border in an attempt to delay the inevitable.
If Mexico ever has a revolution or a disaster like a major earthquake the illegal immigration we're experiencing now will be considered a trickle. That's why it has to be made clear to them they're not the 51st state and they have to learn to solve their own problems like everyone else.
