Initially, wants arise from hunger, but, in due course, the wants turn into hunger. For satisfying hunger, the need can be fulfilled but for satisfying the hunger for needs, there are neither the means nor any power in this world. Today's economists cannot fulfill these; nor any government or its finance ministry could eradicate the hunger for wants.
When the hunger for wants gets ignited, man can never be liberated from unhappiness.
A society with controlled wants is never unhappy. Nobody can grow so rich that he can raise a mountain of wealth or dig a deep ditch that may remain empty. In the society, where desires, wants and consumption are limited, nobody shall remain hungry. On the contrary, where desires, wants and consumption are uncontrolled, the society will remain hungry and will face vicissitudes ups and downs.
