It's back!

Americans these days are way too squeamish about how their packaged meat gets from their idyllic mental picture of the cow grazing in the field to that nice package of beef. They need to try processing their cow on their own and seeing all that wasted beef going into the trash because people turn their noses up on certain cuts their ancestors ate all the time.

All those resources (economic, environmental, etc) were spent raising that cow to just trash a lot of it because the bits don't look like a steak.
