Quotes from Chairman Eli.....

I have a small suggestion for economists who want to see the effects of illegal immigration for themselves. Wherever you are find the local shape up, you know, the 7-11 where the landscaping and building contractors show up between 6 and 10 in the morning to pick up casual labor. Go down there and watch what happens. Then you can close your eyes and claim that these folks are not in your community, and yes, Virginia, they are depressing wages in that sector. Stick around and watch what the guys who don't get picked up do, it ain't pretty. The best way to handle the situation is to swallow deeply and set up a city/county run center with rules, but these are opposed by those who like having mown lawns and cheap kitchens. Like sausage, the populance has no stomach for seeing how it is made.

If you don't know where these places are in your city, then a) you have not been looking, b) just ask the guys who do your lawn or remodel your kitchen. If you can find a REAL old timer, ask him (and it will be a him in that case) how the ethnic identity of those doing casual labor has changed in the last 40-50 years.
Otherwise, don't bother talking to me about it. - Originally posted at Brad deLong's blog

And btw, if you are in a different country, the same rules apply.
