Déjà vu?

I checked the calendar, and yes, this is the year of our Lord 2017.  Why was I confused?  Because I had just been listening to Jeremy Corbyn's speech launching his party's election campaign.  The one where he talked about "taking our wealth back" from the "tax cheats, the rip-off bosses and the greedy bankers", and I thought I was back in the 60s listening to Harold Wilson and his gang.  Nothing much changes it seems.
