Those who accuse the more elderly people here who believe the fifties were 'better' accuse them of looking at the past through rose-tinted spectacles. What they don't grasp is thay THEY are looking at things through 21st century spectacles. In other words they think, for example, that a woman's life must have been hell if she did not have a car, a washing-machine, a television and so on. However, most women then had not even the remotest concept of owning such things, so their lack was not a bar to happiness.
I saw a TV report on a mud-hut village in some drought- and conflict-ridden hell-hole in Africa the other day. A local woman said that things were 'perfect' there - that was how her word was translated - before all the present problems arose. Clearly, the place was never anything BUT a mud-hut village, but back then she considered it 'perfect'! Why? Because she knew no better. Disease and child mortality must have been dreadful, existence could never have been anything other than hand-to-mouth, but she thought it was 'perfect'.
Happiness largely depends on expectation, it's as simple as that.
