I saw this video on YouTube and it reminded me of the story of two engineers, one American and one Chinese. The Chinese engineer was saying, "You Americans are wasteful and spend too much on capital equipment. If you want to tunnel through a mountain, you assemble all kinds of very expensive capital equipment and start to excavate. In China, we get 1000 Chinese on one side of the mountain and 1000 Chinese on the other side of the mountain and say, 'Dig!' When they meet, we have our tunnel!"
The American engineer thought about that and then asked, "What happens if they don't meet?"
The Chinese engineer smiled and said, "Then we have two tunnels!"
