Jeff,
I am an economist. I love Friedman, but he, like a lot of economists, is attempting to reach a quasi-scientific solution with his math. The problem with most economists, is that from the first studies in college, you are innundated with ideas and theories that suggest a central authority is the best solution to all of our problems. The thought process is that human behavior can be quantified and measured and the solutions can be extrapolated from these numbers. Some of this "science" works when you are working in the population at large, but Economics has yet to explain the complex actions that individuals take to create a sense of well-being.
I say quasi-science because the school of economics, while taught in business classes, is rooted in the Social Sciences. That term, Social Science, assumes that social behavior can be quantified, verified, and predicted. I dissagree. Most of the math today is just good guessing, like picking a winning horse based upon statistics. And we all know that Statistics can be manipulated to present one point of view or another.
That is where I disagree with some of your fine research regarding immigration. Talk to any public hospital administrator about the number of babies born in the southwest that are from mothers who are not US citizens or do not have a legal status to the US. These admins have seen double digit expenses since the US passed a law that everyone is entitled, regardless of citizenship or the ability to pay, access to emergency healthcare. In El Paso, over 90% of the newborns are from mothers who, in their final trimester, cross the border on a 'shopping trip' and disappear only to show up at the hospital to deliver their baby. The admins have no way to refuse them and collecting money from a person who gives a fake address and name is impossible.
Just so that you get where I am comming from, most of the statistics that you are quoting are from studies regarding LEGAL immigration. Any data that claims to be accurate that measures Illegal immigration is extremely suspect. Even assuming the teams collecting that data had good intentions, by definition, sample pool for data extrapolation is too small and subject to false information since the subjects being studied are attempting to hide from this type of scrutiny. Legal immigrants can be tracked, interviewed and documented. For most of us against ILLEAGAL immigration it is not against hispanics, despite the fear mongers in LULAC, but it is exactly this tracking and documentation that we want and deserve. We want accountability, trackability,and the unvarnished truth regarding who and where our money is going to.
Anyone who lives in California, Texas, New Mexico, Arizona, and most large metro areas has seen the "barrios" that have sprung up over the last twenty years. This growth of predominatly spanish speaking people (who have forced our schools to adopt second-language classes) has not been because of normal population growth from hispanic families although they typically have larger families that the native US population. It has grown exponentially because of ILLEGAL immigration and the inability or lack of will from our Central Government to stop it.
What a majority (56%-another stat) of Amercans (read US and Naturalized citizens) want is to put an end to open borders and controll the rate of expansion that favors one ethnic group over another. Let's take race out of the discussion and focus on the type of immigrant that we want. There is a difference between an educated engineer from China or India, or even the middle east, from an immigrant with less than a high school education and unable to communicate in our adopted language. One last thought, we have found thru trial and error that the US cannot assimilate 20 million immigrants with their own culture and language in so short a time. the truth is it takes at least two generations to do this. So the arguement that US citizens don't want hispanics is so wrong. We just want everyone to attempt to reach a legal staus, learn the common language, respect the laws, and be good stewards of the rights and responsibilities of the privelege of living in the US.
