Questions About The Economy

Would Wall Street have any money if no one trusted faceless inhuman monsters (e.g. "banks") to invest their money? If Wall Street didn't have any money, would the rest of us have more of it? If we invested in ourselves (e.g. by acquiring and developing resources for production, by using extra income to buy time to develop our skills and learn to create value), would we be freer, more independent, more capable, more productive, and therefore wealthier? If we invested in endeavors we believed in, would the world look more like our dreams?
