European democratic socialism very much has a growth focus, very unclear what a degrowth variant would look like.
In the presence of degrowth, what would a reasonable inflation target be for the central bank? What should the interest rate be? Should the government issue more debt? Under what circumstances should individuals or companies be eligible for incurring debt?
AFAIK, all of these questions don't have good answers so far, whether you are a capitalistic or a socialistic nation.
