When we were in deprivation, income played an important part in the happiness of an individual. Because we lacked money at that time. Try to imagine how if we were starving, we would have been delighted to see a loaf of bread or other food which we could afford. On the other hand, if we were short of money, we would have been turned out of the bakery or restaurant. I think one cannot be happy in that type of situation, and can't help but feel humiliated. So, considering society at present , money is not everything, but we can’t do many things without money.
