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."

It's important that public funds be spent in research directions that are pushing market frontiers rather than working in existing areas. This means funding research not only on drugs but also on areas like life-style changes, even if the profit potential is lower for Big Pharma as you cannot sell that change as you can sell a medicine.

Most venture capital funds are too short-termist and exit-driven to deal with the highly uncertain and lengthy innovation process.

As a businessman, Donald Trump has been associated with some of the worst excesses of a particular style of value-extracting and asset stripping capitalism: set up businesses, let them fail, avoid paying suppliers, use bankruptcy laws to avoid taxes for decades, then set up another business somewhere else. It is this model that is the cause of many problems we see today.

If we look at Germany's infrastructure policy, it has been driven by its mission-oriented focus on green infrastructure. This affects both innovation and infrastructure, old industries and new. The German steel industry, for example, has adapted to the policy by lowering its material content through a 'repurpose, reuse and recycle' strategy.

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

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