While the sock market might be decoupled from production I believe it does reflect (superimposed with some other bubbles) the expectation of capital that no socialist policy or threat to profits can be organized by the labour classes of the powerful countries.

This means that having the greatest recession and a huge pandemic, and still only mostly neoliberal welfare social democratic solutions without attacks on the wealth or means of productions of the capitalists was an experiment with the result that socialists are weak. That governments don't reign in, but try to stabilize and continue as it goes as long as people don't revolt.

We could see the difference between the US, UK and Sweden and Germany, Netherlands and France (later on) and Vietnam, China, Honkong.

We could also look at ressource starved countries like South Africa to see how this crisis would play out in the US in 50 years time.

(Small disclaimer: China showed that it is able to enact huge centrally planed policies and listens to science, this is a show to the world economy that they as part of its capitalist motor will not be slowed down)
