According to two different 'Outlook of M&A' panels I attended in the past two months, corporations have more uninvested cash on their balance sheets than is typical. I mention that because even the money invested by the wealthy into corporations does not necessarily get spent by corporations. This is part of the reason why the argument for 'tax cuts for the wealthy' doesn't hold up under current conditions.
Thinking about it in terms of supply and demand of goods, increasing wealth of the middle class increases overall demand, and increasing wealth of the wealthy increases supply, but only to the extent that demand will support.
