Immigrant Mexicans create jobs! HUH?

Just another sad depressing day for racists really. I mean for years now I've been hearing how Mexicans are coming to America and stealing all our jobs but now I read this and it's the exact opposite.  Down is up, Up is Down.  So I guess the cure to your endless shitty economy is more Mexicans??? whatever works I'm on board.

PS I don't get why the Looney Tunes people chose a fast mouse as a Mexican stereotype?  There has to be some underlying racial meaning to it, but I just don't get it.
