Here is the Lars interview with Tony Snow. You can pick your own favorite part but I think the most telling is Tony's admission that the Bush administration's position (along with the position of the WSJ, Chamber of Commerce, etc) is that our economy needs illegal aliens. It will "tank" without them. (note: He may be onto something, did Mexico's economy start to get bad when they started deporting their Mexicans to us?)
We can call them illegal aliens, guest workers, tomatoes, whatever, they believe that bringing [mostly] Mexicans into this country in as large as numbers as possible is essential to the economy.
This of course is ridiculous. Has Del Monte closed down due to lack of workers? Have they been forced to raise wages? We will always have our own segment of the population to do these jobs. They are starter jobs, they are jobs for the unskilled, they are jobs that may need to move towards automation/mechanization (which would lead to some very good jobs and innovations) and to continue to say that we need an illegal workforce is insulting.
