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.
