I believe you're right and I think this whole program to include illegals for $$ is just the beginning. As the FTAA becomes reality and economies are merged under the American Union I bet this program is expanded into Central and S. America. NAFTA greased the skids for all this B.S.
Mexico's own Social Security system is already bankrupt --- we're certainly not combining the two systems to get either one of them working since both are failing --- theirs faster than ours.
This is a major bailout --- we'll add to our growing large deficits to keep their heads above water a little longer --- then maybe we'll go down under together. Both countries pulled under by massive socialism.
