Ted, I gave sources for all my data. Did you even bother to read it? Ill just point out some of the highlights of the Bell Policy Center's study. According to that study, the fiscal impact in the US of immigrants by type of household in 1994 (in billions of dollars) breaks down like this:
Immigrants only: +$32.4 in overall fiscal impact, +$28.2 federal impact, +$4.2 state and local impact
Immigrants + children less than 20 yrs. old: -$13.3 overall, +$16 federal, -$29.3 state and local
Immigrant + all children: +$29.5 overall, +$48.5 federal, -$19.3 state and local
Immigrants + all children + grandchildren: +$23.5 overall, +$50.9 federal, -$27.4 state and local
The fact of the matter is that there are several studies that indicate that immigrants
as a whole, legal and illegal contribute significantly to the federal government. I find any study that tries to determine the effects of illegal immigrants highly circumspect simply because you cannot dtermine that without knowing the numbers of illegal immigrants. Sadly, because they're illegal, we will not be able to ever fully realize how they effect our spending. However, it can be noted (as I already have) that there are several studies that prove the exact opposite you have. Additionally, I would suggest reading (as I already have)
Immigrant America: A portrait. Additionally, the New York Times published an article in 2005 saying that illegal immigrants contribute about $6-7 billion dollars in Social Security. This is money that undocumented immigrants will not ever be getting back, but is helping out many Americans.
And as for the US companies' impacts on the Mexican economy...Please go and read what I posted previously. I mentioned the Border Industrialization Program, which was supposed to help Bracero workers' readjust back in Mexico, but instead poverty actually increased in the towns that participated. Additionally, NAFTA has severely limited Mexico's competitiveness, and it has hurt rural farmers. The substition policies that are used to "liberalize" an economy tend to leave many farmers without work, because their products are now imported. This leaves many rural farmers without any means to live. To say that US policies don't affect Mexico's is evidence of an extremely lack of understanding of how economies work. There's a very intricate web woven between the two economies, and it's difficult to say exactly how one affects the other, but I would say that they are still linked. Henceforth, if one economy does well (ie, the US), then so does Mexico's.
[/quote]This is absolute nonsense. There are millions of people who would love to come to this country. We can have all the workers we want. That’s what the immigration quotas are for. What we don’t need, and get from Mexico> are uneducated illegal workers who sent most of their wages home (to the tune of a bout 17 BILLION a year) and live off our services. [/quote]
No,
this is nonsense. According to Walter Ewing (reference below), the fertility rate among native citizens is decreasing and by 2020, we will be below the "replacement" level of 2 chlidren per couple. The Congressional Budget Office (2005) predicts that as baby boomers reach retirement age, most of the growth in the labor force will stem from immigrants and their children. This includes illegal immigrants. Since 9/11, we've severely restricted the number of immigrant/work visas that employers are allowed to ask for. This means that many people who may have entered the country legally on a work visa can no longer obtain a legal way to enter the country. They know the work is still there, and they are forced to enter the country illegally. An article in the Washington Post details how fields are going unharvested due to lack of workers (presumably, a large portion of the workers are undocumented):
QUOTE
BATESVILLE, Texas -- J. Allen Carnes needed 200 workers for the onion harvest this year on 500 acres of South Texas fields. The onion business is big in the area, and with only two months to harvest, there's little room for delay.
But Carnes ended up with less than 100 workers and fell two weeks behind, with bits and pieces of the fields unpicked. His income fell about $150,000, a significant loss.
...
Carnes said he couldn't lure workers away from other fields with incentives like higher pay for the late-spring onion harvest because there just weren't enough workers to go around.

So, again. We are dependent on immigrants, legal or not. About 1 in 7 workers (40%) are foreign-born. Restricting access to work visas for fear of terrorists (none of which have ever been caught on the Mexican border...ever) creates more illegal immigrants. The US's immigration quotas are arbitrary, and are mostly skewed in favor of Western Europe. So using the quotas is a poor excuse for why we should build a fence that doesn't even go across the entire Mexican border.

I don't think you're getting my point. The fact that La Raza and the Mexican government and so many other political forces that have an interest in maintaining current levels of illegal immigration are so fervently against the fence, is evidence that these people think it would be effective.
What does this have to do with why I think it's ineffective? I can't answer for La Raza or the Mexican government; however, I did provide evidence that supported my own point of view.
