Another one who spouts off "Buggy Whip". Again, stoplistening to Limbaugh and stop reading the WSJ op ed pages. How many times does this have to be explained. When autos replaced horse and buggys, the workers who made buggy whips simpily used their skills to start makings cars. There was little, if any retraining required, it was basically a lateral move.
People who made buggy whips were artisans. That skill simply did NOT transfer to working on an assembly line, making pieces for Fords.I suggest that you go and find out HOW buggy whips were made; from start to finish and while you're at it, explain to us all, how those making whale oil lamps were so easily moved into positions making light bulbs. Oh yes, and do, please also explain how those who had machines for making rubber products immediately, after WW II, used the same machines and workers to make things out of plastic. LOL
