Anyone who has ever fished for crabs knows that you must remember to cover the bamboo basket when you put a crab in it. A single crab will always try to climb out. However, if you catch a few more crabs and put them in, you don’t have to put the lid on the basket anymore. Now, no matter how hard the crab tries, it can’t get out.
Why is that?
Each crab scrambles for the exit. When one crab gets to the top of the basket, the others grab it with their claws and drag it to the bottom. Then another crab climbs up on top of the pile, and the process is repeated.
This is also the mentality of many people in today’s society: when they are unhappy, they also want others to be depressed. Like the crabs, we wish to drag others down to our level. To be envious and ashamed of others are the greatest follies of human nature.
There is a minor, yet very significant difference between heaven and hell. In these places, God gives everyone a spoon with a long handle with which to share a large saucepan full of food. In hell, people only noticed that the spoon was too long to put food into their mouths; in heaven, people used their spoons to feed each other. Wherever a selfish man goes, hell will follow him.
《螃蟹定律》(螃蟹效应)
钓过螃蟹的人都知道，竹篓内放一只螃蟹，必须要记得盖上盖子，否则它就会爬出来。但是如果你多钓几只放进去后，就不必再盖上盖子了，这时螃蟹再怎么挣扎，也是爬不出来了…
为什么？
因为当有两只以上的螃蟹在篓子里，每一只都争先恐后地朝出口处爬。但当一只螃蟹爬到篓口时，其余的螃蟹就会用钳子抓住它，把它拖到下层，由另一只螃蟹踩着它向上爬。如此循环，没有一只螃蟹能够成功。
这也是现在社会上很多人的心态：自己过得不开心，就想看到别人也不开心；如果自己爬不上去，也拉住别人，让别人也爬不上去。见不得别人好，是人性最大的愚蠢。
天堂与地狱的差别：上帝给每个人一支柄部很长的杓子，共食装满了食物的大炖锅。地狱里众人因杓子过长，无法将食物送入自己的嘴里；而天堂里众人却用长杓子互相喂食。自私的人，所到之处皆是地狱。
