There is never an end to human greed. Some people will do anything to earn more money, grow further , but they do not realise that the happiness this money brings them will be short lived. Every time you harm or cheat another person to earn money, the person may not be able to retaliate immediately, but he or she will mentally curse you and wish you ill. One day, the people who have used unscrupulous means, will no longer be able to enjoy the money they have got, often by troubling or harassing others.
