" These projections don't take into account the economic impact of the Bush proposal, which would allow untold millions of illegal aliens from Mexico to collect full cash benefits for themselves and their families from their home country -- without having to work the required number of years that law-abiding American citizens must work to be eligible for payouts."
This is not true. The benefits would be prorated between the United States and Mexico. From Congressional testimony by Jo Anne Barnhart, Commissioner of the Social Security Administration:
Myth #5: Totalization agreements enable non-citizens who work in the United States for a very short period of time to receive full American Social Security benefits.False. Totalization agreements provide that the United States will pay prorated benefits to those workers who have: (1) between 6 and 39 quarters of coverage with the U.S. system; and (2) a combined work record of at least 10 years in the United States and a partner country. Again, I emphasize, the benefits are paid on a pro-rated basis. Source
