Bliss and happiness are not the same thing. I can mainline heroin and be blissful, at least until the drugs wear off and I start jonesing for my next fix. I may end up dead, but until that happens I'll be experiencing bliss. Happiness is different. It is finding equilibrium with the rest of the world so that you can survive comfortably while doing what you want to do in life. Money represents the resources and services you need to continue living in a modern, comfortable manner. So, no, you don't need to be rich to be happy, but having the money to ensure your continued survival so that you can find what makes you happy in life is a must. Wealth is the basis for happiness, but not happiness in and of itself.
