Huge corporations are acting like nations, global wealth is going to billionaires and ordinary people are suffering. It's set to be a rocky decade - but we can fix it. As the market consolidates under fewer and larger companies, it's increasingly in the interest of private companies to behave like nations. And when the government is bogged down in bureaucratic negotiations and culture wars, people begin to look to nimble, powerful companies to solve society's problems - and to be our moral standard-bearers. It shouldn't be like this.
