A man stops thinking about money only when he starts living in the present. Money is the future; money is security for the future, a guarantee for the future. If you have a good bank balance your future is safe. If you have a good character, even life after death is safe.
The whole world is thinking in terms of money. Those who think in terms of power politics are thinking in terms of money, because money is nothing but a symbol for power. That's why you can go on accumulating more and more money, but the desire never leaves you to have still more -- because the thirst for power is unlimited, it knows no end.
And people are thirsty for power because deep down they are empty. Somehow they want to stuff that emptiness with something -- it may be money, power, prestige, respectability, character, virtue. Anything will do; they want to stuff their inner emptiness.
