Although this story is very basic, it really hits the nail on the head. This is simple Psychology 101.
If you start with a cage containing five monkeys and inside the cage, hang a banana on a string from the top and then you place a set of stairs under the banana, before long a monkey will go to the stairs and climb toward the banana.
As soon as he touches the stairs, you spray all the other monkeys with cold water. After a while another monkey makes an attempt with same result ... all the other monkeys are sprayed with cold water. Pretty soon when another monkey tries to climb the stairs, the other monkeys will try to prevent it.
