Then if there is no plan to increase immigration, where are the working age people going to come from to do the work?
Immigration reform is separate from border security reform. Illegal aliens want to confuse that. So do the Democrats and RINOs. They are invaders not immigrants. These politicians are responding to the demands of illegal foreign nationals not American citizens.
Border security requires addressing two things:
1. Enforcement on the border itself.
2. A rational (as Arlen Spectre put it) means of dealing with the 11 - 20 million illegal aliens here already.
I agree with those who say it is not rational to deal with illegal aliens by "rounding them up." It is not rational economically, socially or politically. What is rational and would be highly effective is to enforce the laws we have on American employers who hire illegal foreign nationals. H.R. 4437, while not perfect, has some very good provisions for doing just that. None of the Senate bills do.
Immigration reform should be considered separately from border security reform. Both in public discussion and in legislative process. It should also be considered secondarily to border security reform.
