I think Piketty does belong there, in that he charts a long-term destabilisation route. So he would belong with Keynes and Minsky.

In general, I think it is important to understand the economics of the urbanised, industrialised, consumer world we are living in and also how it differs from other economies.

I recently read a critique of Keynes analysis of the German WWI debt, based on the post-Napoleonic french states ability to pay 700 million livres over the course of a couple of years. I think a crucial difference (that was not covered) is the mainly rural characther of early 19th century France. If the state mainly extracts surplus from farmers with access to the productive resources it needs, the state does not really need to provide demand to keep the economy going, the farmer's belly does that just fine. But the economy we are in is in contrast extremly dependent on demand being there all the time in order for labour, capital and resources to form up to economic activity.

Bit of a tangent there.
