I can therefore speak about the stock exchange without personal experience, positive or negative. I acknowledge it as the place where the profit principle of capitalism reaches its purest form: where money is made from money. Marx once observed that, unlike production, this business creates no real surplus value but a fictitious one. That surplus may be fictitious in theory, yet it becomes strikingly tangible in the portfolios of certain presidential families when a single statement from a head of state sends markets soaring – or plunging. And when a bubble bursts, the consequences are rarely confined to a single company. Entire economies, even entire states, can be swept up in the fallout.
