Everything is for stomach

Hmmmm finally i pointed out the root cause for most of the problems, and the root cause is stomach. if we ask the question why we are working? Why we are earning? The superficial answer may be different from different people but the ultimate goal of everyone is to satisfy their stomach and live. We may be ambitious in different ways, may be for a person buying a car or a house can be his aim but that is just a passion not the question of survival. Once we are getting the basic necessity that is food then only we think of having other basic necessities, may be clothes and a place to sleep. Once we have these things we think of luxuries, may be better clothes, may be bigger house, may be branded clothes, house in a better locality and things like that. After these things comes the question of owning a vehicle or property or even jewelry or some bullshit which is not at all required. So the only thing which is required is the food and is buyable. Suppose if I quit my job right now I will first worry about my food rather than owning a house or a car. And if I make some arrangements for my food the next moment I will resign from my job and I will go to some forest or to Himalayas and lead the life peacefully. If people stop concentrating on unnecessary things then their life becomes very simple. The reason why people do not think about the basics of life is something I am wondering and not getting the answer. i am sure there are many such questions for which there is no answer available.
