There's a tendency to refer to the 70's as if it was a time of terrible suffering for most people. Yes, there were problems - inflation, industrial action, etc., but that's not the whole story.
My husband was a nurse in the 70's (nurses then were even worse paid than they are now) and I was at home for a couple of years looking after our daughter - and even after that only worked part time. Apart from Child Benefit, we received no additional welfare payments. Although we had very little spare cash, we were reasonably housed, ate two good meals a day, and didn't have to worry about putting the heating on, having a bath or doing the washing. Compare that to nowadays where even two people on reasonable incomes struggle to provide decent housing, good food and a warm home for their families.
