In many countries, yes. People in India and China for instance are on average more likely to not be in severe poverty and subsistence vs 40 years ago, though western-style modernization has caused it's own problems. However most people are less well off in the US than we were in the 50s-90s. Reagan economics seems to have been 'wait, why are we letting the middle class exist? We could just keep all their money'. Seriously though i was completely fucked over by what I mentioned and it's only based on luck that I'm not homeless.
