Fwiw, they don't. They can't. They have vastly more money than they could ever spend on themselves. The majority of their income is just directed back to towards protecting and growing their capital. The flaw in the entire capitalist premise is that this investment is assumed to be an implacable driver of productivity, but as the market is purchased (a free market is either for sale, or it's not actually a free market - it's a manipulated market), investments flow into non-productive asset classes, freezing consumptive momentum (ala Thomas Picketty's book). Moreover, the sale of the market makes zero-sum games more attractive, since, without the protection provided by competition, squeezing resources from others becomes more attractive than creating new opportunity.
