Mexico

This hits the nail SQUARELY on the head. Home run. Grand slam. If the Mexican government would do productive things to foster growth and incorporate into the modern world economy, the export of its impoverished citizens to OUR nation would slow to a rate that would be far more acceptable.

I always suspected that things were bad in the lands of our southern neighbor, but I had no idea they were so bad. 100 million people, 40% in poverty, 25% underemployment (not an official figure) . No wonder they want to come here so badly. An estimated $ 19 billion is sent from "guests" here back home. 3% growth rate is pretty good for a mature economy like the US, but pretty poor in a developing nation. See India, China, etc. all growing 5-7% or better. Interested to see they hit a $1 trillion in GDP this year -- 14th in the world, right behind Canada, and they have 40% poverty! Of course, Canada's population is only 1/3 of Mexico's. Sad, but the incredible income disparity and corruption there have to be addressed, even if we DO build a wall.
