I revised for my A levels in a library lit by candles, because of the three day week.
The 70s were so bright and vibrant culturally, because everyone was poor, and wanted more.
With Maggie Thatcher in the chair, it tipped over into more people doing better, as long as you were not in manufacturing or steel (my SF hated her, and he OWNED a high tech steel company) based on the insight that people work a lot harder for themselves than for the system.
Hence the sale of council houses, which the councils couldn't afford to to repair much less improve. So they were sold. And they were bought by their occupants at pennies on the pound, who did the upgrades that were required to bring them up to decent condition. Once they became owners, they thought like capitalists.
It's a very unpopular opinion here, but capitalism has raised more people out of poverty than socialism. It always will, because people will bust a gut for themselves and their family, if there's a sensible/plausible path set out for them to follow.
