Again, I think it is in the shift of the left from class politics to identity politics. This applies to the Anglo-sphere generally, most acutely to the US but also the UK. Blue collar to white collar. Working class to upper middle class.
This is why the parties of the left have become the parties of the big banks, corporations, professions (always teachers, but now also lawyers and doctors) and even big oil; whereas the right has become populist. Big business is now also “Blairite” (globalized but regulated economy) and has also embraced identity politics and middle class activism through ESG and diversity.
The shift to “woke” describes this shift of the left from class to identity politics and the parallel shift of big business to the left. What was mere insufferable “political correctness” on the left has in parallel mutated into the intolerant cancel culture and authoritarianism of “woke”.
