From what we know generally, I think we can safely conclude a few things. People spend a lot more on housing, transportation, and medical care today than they did in 1949. Production efficiencies have pushed the cost of food and clothing down, but we buy way more pieces of way-lower-quality clothing than before. People used to have a small number of tailored pieces that they would keep for a lifetime. We also waste a lot more food than before, but food still ends up cheaper, meaning the production cost has shrunk enormously.
