I don't believe that bill passed. I know for meat it did not.<quoted text>
I believe the bill got signed requiring food products have to list their country of origin on the labeling. The lettuce may not be from China, but more often from not, it's not from anywhere in the US.
The US produces very little compared to what we use to. These days, the US is primarily in the various services businesses. I suspect this makes economic downturns even more painful for us. Even when times are tight, people still need stuff so they can survive. However, many services are more convienece than necessity.
That being said, we import plenty of cheap farm hands from Mexico, so that keeps food prices down. Personally I wouldn't mind paying a little more for food if we would enforce our laws, but I don't know about others.
