DGR - is there a good signpost for the post Black Death social reforms?
I can't think of anything specific - it's part of English history so all there. The trick is to remember who wrote the history and why.
However, to post a downer, a fact that is never tiring, is that despite the last 1,000 years of history, most (80%) of the land that William the Bastard dished out after Hastings is still in the same families. Which means that it's ownership has survived:
the anarchy;
the signing of Magna carta;
the Black Death;
the Peasants Revolt;
the wars of the roses;
the reformation;
the creation of the Union;
the civil war;
the restoration;
the rise of empire;
WW1;
WW2;
the fall of empire;
flared trousers;
deelyboppers;
When you see it written like that, you suddenly realise why the worlds despots are beating a path to Eton and the Great Universities of Cambridge and Hull
So anyone why thinks Covid is going to change much, beyond a fashion in masks, is probably a little naive. It takes more than a few tens of thousands dead to achieve anything in England.
