Social housing was also easily accessible in the 70s and 80s. It was commonplace for young people to "fall out" with their parents during Summer holidays between school/college/Uni and be given a freebie council flat (along with unemployment benefits!) and then suddenly find themselves reconciled with their parents when it came to September, they were back in education, and no longer eligible for benefits/freebie council flat!
My first boyfriend did exactly that and we "enjoyed" his freebie council flat for the Summer, before he went back into full time education! It was a very common piss take at the time!
Not just those in education either, we had a couple of "single mother" friends who orchestrated arguments with their parents claiming they could no longer live in their family home, so were given council housing, then, years later, they'd "reconcile" and move back into the family home when the child-related benefits started to dry up as the kids got older. In the meantime, they'd spend loads of time at the parents' home, parents would baby sit, etc - i.e. no sign of the so-called arguments, etc. Again, all made up as they knew how to play the system.
Likewise the ones who claim to be single, despite having multiple children by the same bloke over many years, just to get the council house/flat and "single" benefits. Where the bloke claimed to live elsewhere, usually with parents, as they knew they'd lose benefits if they were seen to live together. That's still common today, but it was also common decades ago.
It was the 70s and 80s that started the current "benefits culture". I just don't understand why so many people, especially the older posters, seem to think it's a recent thing - it's not. If anything, benefits seem harder to claim these days as a lot of the "loopholes" are now so well known that the authorities are clamping down and rules have been changed over time (such as stopping the "Summer" benefit claims for youngsters during their Summer holidays!!).
