I was commenting more on the dishwashers and TVs in the 40s. My grandmother grew up in a rural area of Eastern Slovakia in the 40s and they didn't have a dishwasher or TV. Probably because they didn't have electricity. They didn't even have proper floors, just dirt. That's one of the greatest developments of modern time - the extent to which modern technology is everywhere. While TV took ~30 years to become widespread, even poor people in developing countries are using computers and smartphones not much different to people in western countries. 30 years of technological difference shrunk to 2 at most.
