The trouble is that no one quite sees that the very best thing we could do for Mexico is to send their now well trained citizens home.
Suddenly Mexico would have a skilled workforce who knew something about how a world class country worked.
Think these folk would propel a great leap forward for Mexico?
I do.
Basically the ruling class in Mexico will not change of its own volition. But it can be forced to change.
The Mexicans in the USA have had the picture of what a well run country looks like tatooed on the back of their eyeballs. And they'll have an idea of how to get there. Send them back to Mexico and they'll get a revolution in Mexico that'll do that country some good.
The shock troops for that would be the 12 million repatriated Mexican citizens. Having seen what a well run country looks like they would not want to be stuffed back in the old wineskin.
There's something more.
I follow water desalination research pretty closely. While water desalination costs have dropped to about a third of what they were 15 years ago--the rate at which prices will drop over the next seven years will accelerate considerably. imo in even the next five years we will see desalination costs drop to 1/10th of today's costs.
Basically, the foundations are being laid today to make it economically feasable to to turn all the world's deserts green. (The proper way to look at this is to recall that cars, tv's and computers were at first rich men's toys but when prices came down they changed the world. Desalinised water is still relatively speaking -- a rich man's toy. But when the price drops sufficiently--desalinised water will change the world--because most deserts are right beside the ocean.)
imho cheap desalinised water will do for the republicans (if they can get this on their agenda) what the great dam building projects & the tva of the 1930's &40's did for democrats because 1/3 of the US is deserts. We would increase the habitable size of the USA by 1/3.
Dirt cheap desalinised water will also do things like make it possible to double the habitable size of Mexico.
And desalinated water in tandem with repatriation of now skilled Mexican citizens would propel Mexico into being a world class country.
