You might also compare the natural resources of Mexico with the USA's -=- and how number of billionaires in Mexico competes with number in Great Britain --- obviously there is no excuse for the level of poverty. Mexico has already dumped one-fifth of it's population on the USA --- but there is no end to their demands --- Vicente Fox is all the more aggressive in what he requires.
Massive immigration is the result of social injustice in Mexico --- it results from instability and leads to more instability. This is a vicious spiral now --- the more people they send us, the more people they demand to send us. They never intend to end the corruption, they never intend to build up a strong middle class or allow the peasants to reach the middle class or have access to the great wealth of Mexico. This is the elites' way of preventing a long overdue revolution or changing the underlying conditions that lead to one.
