Would you approve of the comparison to postwar interventionism if you saw large scale nationalizations in key areas? Like if big EU energy companies, say EDF and Uniper, were to be nationalized?
Post war interventionism included energy utilities, which in many cases were rebuilt from the ground up, but also transport, rail in particular, telecommunication, extractive and heavy industries - and it happened in economies with a much smaller tertial services sector.
I don't know what the equivalent contemporaries would be, but in any case we would need to see public spending or nationalization on a scale incomprehensible to the current neo-liberal european business climate, not just some puny guarantees & price ceilings, which are not very sustainable anyway.
