Cold water flats! What was the capital city of the world till WWII had no hot water in their apartments! They used so much coal just to keep things running, grey moths evolved into black forms just to camouflage against the trees, as even the forests were covered in soot!
Skiffle bands - which were wannabe all-American music bands - used cheap acoustic guitars and literal tin cans because y'all had no electricity to plug into nor money to buy legit instruments. And that was in LONDON! Life in the Hinterlands was still pony driven Medievel. Their motto was, "Well at least we ain't Czarist Russia, ya daft codger!" Which they weren't, as they were a good solid decade advanced!
Mind you, this was Britain, which was the most 'modern' country in Europe at the time. They were still wearing woolen socks!
