Why don't you try saving for your retirement? That way, you can support yourself and not require a deluge of third world immigrants to finance your golden years.
(also, on a practical note....if you think that young mexicans are going to tolerate sky-high taxes to finance retirement for a bunch of white baby-boomers...then you are naive in the extreme)
One thing people don't realize is that one of the fastest growing immigrant group is people over 60. It was stupid for anyone to believe the immigrants would abandon their own elderly. They don't ---they are bringing them here to get them on Medicare, Medicaid, and SSI. Also the immigrants will also demand their Social Security payments.
The other thing people don't realize is that the immigrants actually paying into Social Security are legal and have SS numbers ---they tend not to have anymore children than Americans do. Illegals get paid under the table and Social Security isn't taken out. The only people who can afford many kids are the welfare mothers.
