It doesn't and it should be very disturbing that government is trying to gain such a foot-hold in this country. If Fox, Grijalva or any of the others care anything about the Mexican citizens, why aren't they doing something different with the families in those photos? Why don't they work on who is murdering young women and girls from these poor neighborhoods? Where is the concern for their rights?
What Mexico wants is control of it's safety valve which is the US because the corrupt know the minute it's closed, their ability to make millions and billions of dollars comes to an end. They don't of course care about Mexico but they don't get the same deal in the countries they will exile in.
Contrast the Mexican five former presidents' yearly salaries of $5million each with these little homes made of discarded wood pallets (BTW---the government destroyed and confiscated the wood and didn't reimburse it's citizens even for that, some of them had $100-150 invested in those houses which they lost). Mexican former presidents make 10 times a year more than US former presidents ---and in a land where people are lucky to make $4.50 a day.
