I hear ya. How many wealthy and middle class illegal aliens can we absorb? If we could find them, it wouldn't be so controversial. But you and I know there's no chance any of those arriving will be making enough to pay for that entitlement bill due in a decade's time. By then President Bush will be long gone and it'll be another President's headache to deal with.
The trick is to get cheap workers abroad in China and India etc. to make stuff for us old sick geezers, and we will pay for it, albeit at cheaper prices, by gradually liquidating our collective assets, which the Chinese and the Indians will buy. At the time of the final exit of the final baby boomer, they will a very large chunk of the US stock market, hold most of the US debt, and own much of the most desirable real estate. That is the grand unified theory that squares the circle. After that, things will gradually equilibriate, and ownership will gradually become more balanced again.
The trick after that is to get the Muslims/ Africans in high birth rate places to become economically productive. If they don't, then the planet has a problem, because the world's supply of productive cheap younger workers to support the aging geezers now in large supply just about everywhere, given rapidly declining fertility, will be very thin on the ground, and that standard of living of the geezers will collectively go down the toilet. The good news is that I will be long gone when that happens. I'm all right Jack.
