I don't know where you were during Mrs. Thatcher's government but there were many ethnic groups in London and the Midlands where I lived and worked with them. There were public school men but also many grammar school boys, as Michael Howard once told the supercilious Tony Blair in the House, and plenty of women; Mrs. Thatcher, a grocer's daughter was a grammar school girl and Oxford educated. One of the worst things Labour did was attack the grammar schools; they were the way to help those who aspired but came from poor backgrounds.
The three day week was Edward Heath, and due to the strikes, which ruined the car industry and the mines; the unions thought they would bring the country to a standstill instead of which they, not the government , destroyed their industries.And they are attempting the same thing now.
The main trouble at present that I see is laziness which has developed since covid; work from home, work life balance, part time work and early retirement. Plus. school refusal. Then the burgeoning welfare state, meant to be a safety net, not a cushion; now a mattress.
At present the country is being governed by a metro-bubble, who are certainly disconnected, and a pretty poor job they are doing, after all their unrealistic raising of expectations. I don't think we will descend into anarchy, but this government needs to take stock, and soon.
