It is used to make money for the company so they can grow and HOPEFULLY improve themselves for their customers and their employees.
What I see happen is that because companies are so tied to KEEP growing, or at least monetarily keep growing that they cut costs and those costs and NOT good for the employees or, say the environment or say their suppliers and their bottom lines. The Pharma and helthcare companies abide by the same thing. Insurance companies... same thing. And screwing their clients by any legal means possible is in their deck of cards. OH!!!!! And bribing the Feds.... errrr..... Lobbying the government to win business.... to win sales no matter WHAT the cost... just so the cost of their stock rises.
Stock holders expect the company to earn more and MORE and MORE each quater of each year so they get wealthy. They dont care what or how that company makes a profit.
Bottom line... has Wall Street had a mostly negative influence on America?
