You equate obesity with lack of poverty? Mexico's economic conditions have changed little, and the obesity surge in the past 15 years or so can be directly tied to fast foods, junk foods and sodas and such, along with replacing the corn tortilla with more and more flour tortillas - something we introduced them to.
I guess it must be all the poor skinny ones who are sneaking across the border.
When there were four billion people on the earth about half of them were severely malnourished . Now there are over six billion and only 700 million are malnourished .
Wherever do you get your figures?
No matter, when there are 500 million to 1 billion people left and 95% or more of them are slaves to the elite who have divided the spoils, commerce as we know it among the masses will have ceased to exist. It will be one huge company store.
