So in Europe, it is standard govermental procedere to transfer 20% ownership of big corporations to employees? It is standard govermental procedere to have 45% of BoD elected by workers?
It is absolutely not standard in Europe, so have my upvote. Although there are exceptional cases such as Germany's, where large enough companies must assign a percentage of the BoD positions to worker-elected union members.
I'd probably put Sanders left of plenty of European social-democratic parties, roughly landing around the positions of contemporary left populist parties (Podemos, France Insoumise, old Syriza), perhaps somewhat distanced from Eurocommunist parties.
