Mexican authorities discover 219 migrants in truck So the Mexican government does not have a problem deporting?

That's their double standard.You should see how strict their immigration laws are.Most of the illegal immigrants that make their way to the USA via mexico are from a certain socioeconomical background so in all actuality,the people who run the country(the oligarchy) really want to get rid of them.Just go to Latin America and you can see.Who works in an air conditioned office and who's pushing a "raspado" cart.The guy pushing the cart is the one who will risk immigrating illegally.
