Well I agree that the numbers you are citing are too many if true. The problem we are facing is one of demographics. We are rapidly approaching the retirement of 35 million boomers. We already have an unsustainable retirement population and this new influx is going to wreak havoc on the country unless our tax base is somehow expanded and we are just not breding fast enough to make up the difference. As I said earlier on this thread, if we have to import workers then I prefer socially conservative people rather than those that have lived in what amounts to European atheist countries. Hispanics and Asians are the only minority groups that are not a guaranteed liberal voting block but the rhetoric some are using in this debate is making many of them wonder if they are really welcome in conservative circles. Don't think for a moment that legal Hispanics are not watching this debate closely.
As to this number of 20 to 60 million. I dont see any mumbers approaching 60 million in the next 20 years. I have read the Heritage report where alot of these numbers are based on. I find their reasoning a bit flawed. I think the CBO numbers even if a bit low is closer.
