I don't dispute that in the 70s there was a peculiar attitude to work, with dreaded words like 'demarcation' holding sway, and rigid lines that tended often to curb entrepreneurial enthusiasm. However, as you said, "nothing happens in isolation" and those less-than-savoury 70s attitudes to work arose because of the earlier exploitation of workers that was so widespread before WW2. Thatcher was the counter balance to that, but she went too far the other way : her government was deliberately antagonistic - even militant - towards the miners, who like the steelworkers and shipbuilders got virtually no help once their community's jobs had gone. She encouraged people to buy their own council houses (good) but then didn't build more social housing (bad). She was a virtual slave to free market economics courtesy of Keith Joseph, and any liberal tendencies in her government ("The Wets") were ruthlessly purged. She did help get our economy back on a sounder footing (though being a member of the EU also had a lot to do with that), but the price we as a nation paid in societal terms was high. Too high.
