I am not talking about communism. Nobody on today's political left spectrum of is seriously talking about communism. This is about socialism, or social capitalism.
I think this is an example of the creeping effect though. Socialism isn't some grand cure for things. There'd still be countless problems in society (and arguably even more than today) and so you'd have some people claiming then that the solution is to go even more leftward towards communism (as indeed some want to start with today) while others would be arguing for more privatization, as is again already happening in most/all countries with various large scale social programs.
The most fundamental problem we haven't isn't the system, but the people. It seems that all electoral systems are unable to avoid putting people in power that shouldn't be there. Look at basically every Western country and we all seem to be ruled by idiots who have no real vision for anything besides being in power. And so it's not exactly a shock that you get 'systemic' failures.
The same was true in the ancient empires with their dictators and emperors. During the time of enlightened and wise leadership they've have remarkable cities and justice that are inspiring even today. But then of course during times of power hungry hedonic idiots ruling, the societies would crumble and injustice would be ubiquitous. It was never about the system - it was always about the people. The goal should be to have a system that picks great people, but we seem yet to have discovered that. And indeed it may not exist. People that want to be in politics are the last people that should ever be allowed in politics, which poses quite the dilemma!
