I’d argue that each time, things get a little better.
Sure the worst part is always the worst we’ve ever seen, but we take what we learned from that and create new systems. Plan A starts well enough, until money and power corrupt it, it gets bad enough to revolt and now we try plan B. Plan B will eventually corrupt, but, it’s better than plan A ever was. We’re getting closer, but it’s a trial and error process that happens over centuries, so it’s going to take longer than we’ll ever know.
