Yep, that's why they are cheap labor....
I'm not saying it's not a problem, I'm not saying it's a good thing.
I'm saying that the boomers didn't have enough kids and we have to import cheap labor. Social pathologies come with that cheap labor.
The articles lament that fact and suggest no alternative source of cheap labor.
First of all, the labor is cheap only for the employer. The taxpayer must subsidize all of the other costs and the long term impact will be a Balkanization of the country along linguistic and cultural lines, i.e, the end of this country as we know it.
The US has the highest annual population growth rate of any developed country in the world [.89%] and our birth rate is 2.09 or at replacement levels. Even if we stopped all immigration tomorrow, we would still increase our population by 62 million.
You obviously didn't read or didn't comprehend the article I linked to you about the demograhic impact of immigration and how it affects the labor pool. Check out the sections on the impact on an aging society, especially just changing the retirement age from 65 to 68 and what effect that has on the availability of workers. Also, at the current level of net immigration (1.25 million a year), 61 percent of the nations population will be of working age (15-66) in 2060, compared to 60 percent if net immigration were reduced to 300,000 a year.
There are 54 million Americans of working age [15-66] who aren't working. They are in school, stay at home moms, disabled, etc. but many of the jobs filled by illegal aliens are because of the economics involved, not the availability of labor. The employer does not have to pay high salaries, benefits, SS, etc. to what amounts to slave labor. They realize the bottom line benefit, but people are not widgets that can be disposed of. The societal costs are enormous. You can drink the Chamber of Commerce Kool-aid about worker shortages, but the only real shortage is exploitable, disposable slave labor.
In October, unemployment rates for the major worker groups--adult men (4.3 percent), adult women (4.1 percent), teenagers (15.6 percent), whites (4.2 percent), blacks (8.5 percent), and Hispanics (5.6 percent)--showed little or no change. The unemployment rate for Asians was 3.7 percent, not seasonally adjusted.
