Profitable mass production has come from satisfying the needs, wants, and desires of the mass of humanity. If in past times the mass of people bound to the land were compelled to serve the wants of the few who through conquest and plunder lived as the lords of the manor, under free-market capitalism, those who take on the role of entrepreneur and enterpriser have no source of personal wealth other than their successful catering to the wants of the many - the large consuming general public. That means all of us.
