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.

We should be investing where the public returns are greatest - that is in innovation.

Too many politicians seem to reach for 'infrastructure' as the default answer to investment, as if roads and bridges were the answer to everything. Even the IMF and the World Bank seem to mainly offer infrastructure spending as an alternative to austerity, although they are right to focus on the need for investment.

If we want growth today to be more innovation-driven, more inclusive and more sustainable, then we need a more active state, not a less active one. Yet we still hear the dogma that we should just fix market failure by focusing on science and infrastructure, and to "level the playing field."

People work hard and companies make big profits, but employees don't see that they share in the wealth they help to create.

There is a lot of flesh to be put on the bones - but there is at least an opening for a more pragmatic, less ideological debate about how to build economies that work for people, within the limits of our planet.

Fixing markets isn't enough. We have to actively shape and create them and tilt the playing field in the direction of the growth we want.
