If a wealthy businessman has no customers who can afford his products, he will not recover either.
This becomes the crippler of Reaganomics: Supply doesn't drive production, DEMAND does. No one makes a factory to produce widgets that nobody is going to buy. It matters not how much money you fork over to the rich and the 'entre-manures', they will never provide any jobs for anything if there isn't a demand for the crap they want to make.
Not that demand alone is sufficient; it must be balanced. And so it is certainly not only a matter of supply.
