I heard an American story here. An American rich man can't control his son who doesn't work properly. He calls his friend and asks his friend to arrange a basic level job for his son in his company. The friend says, no problem. Come to our group as vice president. The rich man says how can that work? Let him start with basic work. The friend said: then be the vice president of the New York branch. The rich man stressed again: his son can't do this. He has to start at the basic level. The friend said: people who do basic work have to have two master's degrees and master three foreign languages. Your silly son can't do it!
