NnHmmmmm, some truth in that Monty. From what you've said elsewhere you're a year younger than me so we hit the seventies at about the same time.
I'd say the advantages you mention in terms of educational support and final pay pensions were the product of post war legislation and were equally relevant to the fifties and sixties. Plentiful jobs were a feature of the sixties too.
What marked the seventies down economically was the problem of rampant inflation. Mortgage rates went up over 13%, wages rose but were soon eroded by such rapid rises in the cost of living. There were attempts at government wage restraint - largely unsuccessful - and the value of the pound slid against major currencies. We were held to ransom by OPEC and petrol supplies dried up causing interminable waits at the pumps. Industrial relations were at an all time low with stagnant old fashioned management practice and union radicalism. It was a time of three day weeks and power cuts. England looked and felt "seedy" in my mind. We were trying to maintain great nation status and failing badly.
I left England for the U.S. early in 1975. Not because I was dissatisfied with it all. An opportunity was offered and I took it. But America seemed so much more affluent and my standard of living rocketed. Everything from getting a phone installed to getting a loan to buy a car seemed to work so much more efficiently.
Clearly there were good aspects to living in Britain in the 70s and I believe economically things improved. I was back for a few years in 1978 and it did seem more stable and affluent.
I'm not really debating your well made observations based on what you experienced; just offering a different perspective. As you say the question is about individual preference rather than a macro level observation.
