In order for the economy to expand money has got to be made available for business creation and expansion. There are two ways to get that money: Equity and debt. Both require someone to provide the money. The poor cannot spend money on goods if there is no one making the goods. Further, they don't have jobs unless someone provides them. The money necessary to do these things comes from the debt and equity markets, both of which rely on people with excess money. Investing in the economy is what creates the goods people spend money on. To have one you need the other.
