It's not like it was a hellhole, but compared to today the only positive metric that stands out, maybe, is that the 1950s future held more promise than the 2020s, at least for some.
Medicine has become better, so have cars; we have computers, satellites, and internet now, mobile phones - all things that simply weren't available to consumers (or pretty much anyone) back then. The overall standard of living of the average Briton in 2023 is massively better than in 1951. Maybe in 2019 things were even better than in 2023, but pretty much every decade after 1950 brought substantial improvements that all compounded on each other.
Occasional setbacks are inevitable, but there overall long-term trend for the average person is undoubtedly positive.
