- Social Security actuaries estimate that a totalization agreement with Mexico would have a negligible long-range effect on the Trust Funds.
- Costs to the U.S. Social Security system are estimated to average about $105 million per year over the first five years. These costs are for additional benefits to eligible U.S. and Mexican workers and reduced Social Security tax contributions under the dual taxation exemption.
- To put this in perspective, in 2002, costs to the U.S. system for the existing agreement with Canada were about $197 million.

There is NO way that there's more Canadians working in the US than Mexicans - no freaking way.
So throw that $105 mil in the garbage and triple (at least) the $197 mil paid to Canucks, which is $591 MILLION. There's also no way in HELL that some 30 million Mexicans making minimum wage and below, could ever, ever, ever pay that much INTO the system. Their whole extended family will be sucking the SS system dry in five years - period!
Really, I agree, the idea that this will have negligible impact is ludicrous. Just as an example, my co-worker has a wife and 7 kids in Mexico. If he is/became eligible for SS benefits, would not his family qualify for survivor benefits? Now, in the name of "fairness" I can see that anyone who paid into SS would feel at least entitled to what they put in. However, when someone is supporting their family on considerably less than it would cost them if they all lived here, plus is able to take advantage of free services here (he goes to a free clinic and recently had a $6000 hospital bill get disappeared for him), I get a bit angry that they may be able to retire to Mexico and draw a SS retirement check. An illegal alien I don't feel is entitled to anything, regardless if they paid taxes or paid into SS. You can't selectively chose which laws and regulations you going to obey/enforce.
"There's also no way in HELL that some 30 million Mexicans making minimum wage and below, could ever, ever, ever pay that much INTO the system."
30,000,000 mexicans x $4/hr x 2080 hr./yr x 15 years
= $3,744,000,000,000 Gross income
x 12% SS contributions = $449,280,000,000
Even over the first 5 years, it would still be over $100 billion. Of course this is all fiction, since there are nowhere near 30 million illegal alien workers in this country.
