It's a real puzzler to figure how the USA built skyscrapers, manufactured hundreds of thousands Jeeps, trucks, tanks, ships, bombers, fighter airplanes to win WWII, then rebuilt Europe and Japan, supplied the world with automobiles, telephones and TV sets, built the Interstate Highway system and then put men on the moon when it was mostly those stupid, bumbling white guys doing the heavy lifting.
Just think how much better we could have done if we had some of those rocket scientist black and white females and black men doing the work instead of wasting their time making TV commercials and helping stupid white guys find the door handle.
