"On the subject of the 70's, [...]"
In my nostalgia the 70s were a period of great promise. Great job in computing, good pay, left home for my own flat. Social mores were rapidly becoming more liberal. The Churches had lost their social control - and trendy clergy admitted to doubts. Tugging your figurative forelock was no longer expected in many places.
Admittedly most of the strife of the 3 day week and "Strike Britannia" was seen through the lenses of overseas postings - reading newspapers and Punch a few days or weeks past the events.
Then along came Mrs Thatcher with libertarian financial policies for the rich - and regressive non-libertarian social policies for everyone else. She was disappointed to discover she couldn't recreate the apparently philanthropic Victorian era just by passing laws.
Interesting times for historians to pick over like the proverbial Curate's egg.
