I think that the 60s and70s was the happiest time for our generation. There was still that idea of inclusiveness and society, that helps oil the wheels.
I remember it as being a happy time personally in some ways, but:
a) finding work was difficult, DH was out of work for 4 months (a very worrying time and we had to move away from where we loved)
b) it may have been happy for many of us because it may have been when our DC were born
c) there was no internet (although there were computers) so people were more insular and not able to express grievances etc online with the world
d) it was also a time when Local Government was reorganised and I remember a lot of 'snouts in the trough' when that took place. I was not one of them so did not benefit.
Perhaps we were happier because we knew no better? We did not have so much access to other people's opinions except through the media, tv, newspapers, radio.
