I'm guessing that most of these people are students or visiting professors here for a limited time. Most of the students come here to learn from the best and then go back to help their own countrymen develop a better life. But they get greedy and want to stay here where they can make more money. They are saying 'to hell with my country, it's all about me'. And we are complaining about this. What's wrong with this picture?
