That's because we're the good guys.
(Of course, being good buys, we enter a war and fight it to a stalemate.)
If our goobermint cozied up to Castro and Chavez our leftist-socialist state department would be all over these commies with kisses. Our security (which is so woefully inadequate now) would resemble swiss cheese as we'd be sharing everything with our new commie friends.
Forget about our CIA. It's been a socialist think tank for decades.
Back to the Mexicans.
Their country is indeed a cesspool on a par with Namibia or Zimbabwe (or is it Zimbabme?)
NAFTA was rolled out to solve all the economic problems of Mexica. After all, the U. S. has been bankrupt for eons and has loaned money to Mexico that would rebuild the Bush-destructed New Orleans and feed all the lazies for years.
The problem with NAFTA, among the myriad, is that now goods are manufactured in China, transshipped to Mexico where the goods are labeled "Made in Mexico" then shipped up to el Norte to the throngs of eagar and simple American consumers.
As long as the Mexican government continues to perpetuate itself in a form of incest, Mexicans will leave and come North.
Erecting a wall, deporting all illegals will send them back to do combat with their filthy government, but then they'll end up like Venezuela or Cuber.
It doesn't matter. We should be tired and sick to the point of puking to let our hearts bleed a little more for someone else. Deport the whole lot of them, seal the border and recall our ambassadors to Mexico, Venezuela, Peru and Ecuador.
Sounds good to me.
You can always invite the world in. You'll never get them out.
I'm still awaiting hearing about Mexico (likely the government itself in some form) selling "trips to the U.S." to anyone around the world that has the cash.
A new U.S. immigration system is now in place. Why spend time in long lines? Why risk the U.S. Government saying "no?" Why fill out oodles of paperwork? The Mexican government has eliminated all of that.
Should be interesting what kind of riffraff gets fasttracked for instant immigration status (effectively) over the coming years.
