Our politicians are stupid. And the Mexican government is much smarter, much sharper, much more cunning. And they send the bad ones over because they don't want to pay for them. They don't want to take care of them. Why should they when the stupid leaders of the United States will do it for them?
One of the big questions in the climate change debate: Are humans any smarter than frogs in a pot? If you put a frog in a pot and slowly turn up the heat, it won't jump out. Instead, it will enjoy the nice warm bath until it is cooked to death. We humans seem to be doing pretty much the same thing.
