You are making an argument for increasing the numbers allowed in as legal immigrants. Might I suggest that we can get all the folks we need, with degrees too, without bringing in more Mexicans and Latin Americans.
You could suggest it, but I know it is not true. There are not 10-20 healthy American youth out there that are willing and able to do these tough physical jobs at any price. Like it or not, without illegals most of these jobs would not get done. Lousiana will not get rebuilt without the help of immigrants.
