The tired old email in the OP that's referenced at Snopes is about a measure that did not pass. It's not the same as the more recent issue of a US - Mexican Social Security Totalization Agreement.
I learned of the Totalization Agreement in January. According to reports, a bipartisan seniors organization called the
TREA Senior Citizens League filed a Freedom of Information Act lawsuit to force the Social Security Administration to release a copy of the US - Mexican Social Security Totalization Agreement that was signed by the social security commissioners of Mexico and the US in June 2004. Junior has not yet signed the agreement. Once he has, the agreement would sit in Congress for 60 session days. If both houses of Congress do not take action within that time to oppose the agreement, it can move forward.
You are correct to say that the US has such agreements with other countries. There are 20 of them, which are listed
here. There are reasons to conclude, however, that such an arrangement with Mexico would not be as advantageous for the US as are these 20.
Economies in all these 20 nations are more prosperous than that of Mexico. I will use
per capita GDP as a rule of thumb for comparison. Chile is ranked lowest of the 20, at 57 out of 181 listed nations. All of the 19 others are ranked 37 and above. The US is 3. Mexico is 65.
Another objection is that the retirement systems of these 20 countries are similar to that of the US Social Security program, while that of Mexico is not. Americans receive benefits after working for 10 years, but Mexicans have to work 24 years before receiving any benefits. Mexican workers receive back in retirement only what they actually paid in plus interest, whereas the U.S. Social Security system is skewed to give lower-wage earners benefits greatly in excess of what they and their employers contributed. And only 40 percent of Mexican private sector employees pay into their retirement system, compared to 96 percent of public and private sector employees in the US.
69% of the illegal aliens living in the US in January 2000 were from Mexico, according to a
study by US Immigration and Naturalization Service. None of the 20 current Totalization Agreement countries individually accounts for even 1 percent of illegals in the US.
The proposed US - Mexican Social Security Totalization Agreement is unlike the 20 current agreements with other countries in that it offers no parity and the potential ramifications are enormous. With the magnitude of new US Social Security beneficiaries that is likely, it is ludicrous to proceed without any serious discussion of the cost, and from where the money will come.
