A social crisis due to asset price bubbles in place of an economic or debt crisis?

To stave off an economic crisis ( huge rise in unemployment and in corporate bankruptcies), OECD countries in 2020 are implementing a highly expansionary fiscal policy. To stave off a debt crisis (financing difficulties, rising interest rates), they are implementing an ultra-expansionary monetary policy. But it must not be forgotten that if the highly expansionary monetary policy leads to asset price bubbles (equities, real estate), a social crisis may ensue. In particular, real estate bubbles increase housing costs and make it even harder for middle classes to access housing in cities.
