It depends on the timespan and comparative frame you are thinking about. If we limit ourselves to post-WW2 MAD world, there are much different overall trends in quality of life than starting in the middle ages or from colonial times, where many people did not enjoy the rights or luxuries modern people would, not in small part because they couldn't, technologically speaking. It's easy to compare modern poverty to peasantry and say we have it good now, but it doesn't address modern problems in a meaningful way.
