I would define them slightly differently now in 2026, because those policies, formed a long time ago depend on an individual nation actually having control over for example national industries or the utilities, which are now owned internationally.
Big firms outsource work to poor countries where labour is cheap. We don't have the powers to nationalise many endeavours. It the reality governments have to work with. Along with events like Covid, which had not been conceived of previously.
And we are really up against it with the Trumps of this world - shoving tariffs up or down at a whim, starting a war which will put prices up whatever we do. Which is why I believe in alliances like the EU, working with them for mutual interests, never mind our actual defence, which depends on a NATO we also belong to. And realistic policies, without losing in our hearts the basic principles, which is that wealth should be more shared out than it is, to provide the health and education and social care we aspire to.
