Of course they reinvest it in something. They reinvest it in the same trivial businesses - Farmville, Candy Crush, etc. It's a self-perpetuating cycle of inanity.
I'd like to think that this is a transfer of wealth from idle hands to productive hands, since I have to assume that at least a portion of the business owners behind those cash machines you mention won't just sit on a montain of money, but rather reinvest it in something. But perhaps I'm too optimistic.
