Noooooooo.... when a >>FOREIGNER<< holds a job that an american could do, the job has been exported just as surely as if it were being done by a chinese in china, no matter where the foreigner is. The unemployment rate for >>Americans<< stays up.
The number of jobs is not static. This has long been proven. Might as well argue against gravity or evolution, but I am not going to waste my time with you on that.
No, you just periodically toss in a bunch of names, substituting argumentem ad authoritatem in lieu of arguing the issue. And there's one thing you don't get about the illegal alien invasion - you keep trying to look at it in purely economic terms, but it has great political, social, legal and other implications.
Care to make arguments for any of those because all you've done is tell me what you think and said it is the truth?
As for the other terms:
political- I don't care much for political games- it might be weird for politicians to accept something illegal and they shouldn't but we as a people sure can.
social- accepting immigrants- a cornerstone of this country, no problem there
legal- no implications really- this goes with the politics
moral- I am not the one denying people the opportunity to better themselves. their communities, and their situations.
other- what do you want me to explain?
The economic term is really the most important here, primarily because it interweaves the other terms and can be measured objectively.
