Companies prefer to put money in the pockets of shareholders or to hoard cash rather than to raise wages or invest.

Green is not just about renewable energy. It's also about creating a new direction for the whole economy. This requires government to step up, not step back, creating the kinds of mission-oriented public organizations that will enable us to tackle climate change - as ambitious as those that got us to the moon. It also requires the financial sector to be less short-term since we know that short-term finance has distorted incentives and directions in areas like biotechnology.

It would be a mistake to overstate the similarities between the Brexit vote and Trump's win - but there are common themes, not least in the rallying cries that the winning campaigns used. They focused on a supposed economic threat posed by outsiders, as immigrants or as trade partners. This fuelling of anxieties underpinned a narrative centered on the need to "regain control," whether of borders or of economic forces.

Shareholder value theory - the destructive idea that companies should be run solely for the benefit of shareholders - has led to financialized businesses that do not invest in the areas that will lead to future growth or the invention of useful new products.

Brexit and Trump have brought the problems of capitalism into sharp relief, but both are only making things worse. Take the investment challenge - businesses invest where there they see technological or market opportunity.

Another similarity of Brexit and Trump's campaigns was an attack on so-called elites. This is not so much a failure of capitalism as of its high priests in the economic profession, for which we must all take some responsibility.
