It doesn't look like you have got it in focus about
"where this leads". Just to put you in better focus, your argument is based on hype, rather than reality.
A realistic assessment of this "immigrants are needed" idea appears in a report of the Social Security Advisory Board, following a September 7, 2005 meeting with noted demographers, economists and immigration experts, to examine the long-range impact of immigration on the Social Security system.
The experts at the end of the day’s hearings summarized their position as strongly urging that the Advisory Board not look to immigration as a means for strengthening the system in the long run.
As a result of that expert testimony, the Advisory Board wrote,
“While recognizing the importance of immigration to our future patterns of economic and population growth, the Social Security Advisory Board does not view immigration as a panacea or free lunch for saving Social Security.”
While increased immigration might help the Social Security Trust Fund in the short-run, the reason it is no solution in the long run is the following:
1. Immigrant workers age too. They then become eligible for benefits. More foreign workers result in increased future payouts. This helps only as long as larger numbers of immigrants are being brought in than are retiring. Soon, that won't be the case, and just the opposite will be.
2. A majority of immigrant workers take low-wage jobs. Because the Social Security System is redistributive, it pays out more to low-wage workers compared to their contributions, than it does for high-wage workers. That means that the more low-wage immigrants who are admitted to work in our country and become eligible for future payments, the greater the burden will be on the future workers to support those retirees.
As George H. Bush would say >> BAD! BAD!
