Some of those figures can be very misleading, since they use the standard 6-digit commodity codes and the size of an industry's activity can depend on the methodology used to identify the commodity groups. "Petroleum products," for example, seems to be a very large classification including a number of different products, while "light trucks" may be a subset of either transportation equipment or passenger vehicles.
I also find it hard to believe that slaughtered animals are really among the country's top manufactured products. Maybe they're including road kill and all the birds killed by windmills here. LOL.

It IS hard to believe, until you drive around the US and see all the empty office buildings, condemned factories and multitudes of people hanging out on street corners, then it becomes a bit more believable... and frightening.
