This is a cartoon produced by Harding College in 1948, but it seems particularly relevant today also. Ken says it's required viewing by all, and I agree with him.
My only criticism is that it uses the invention of the auto as an example of "American" ingenuity. (It doesn't specify that this is America, but it obviously is supposed to be.) The auto was invented by a Frenchman (steam-powered) and a German (internal-combustion engine).
It's still a damn good cartoon.
