You're tilting at windmills.
I didn't claim our current system is perfect or uncorrupted (the phrase least worst system clearly points out that our current systems are flawed). I don't think social improvement (however you define that) inevitably leads to some kind of totalitarianism, but I do think people claiming to have all the answers to creating a fairer society have turned out to be tyrannical more often than not (e.g. Lenin, Mao, Pol Pot, Stalin etc), and I prefer the gradual, consensual move to socialism we have in Western Europe (a form of capitalism tempered by social justice and redistribution, far more equitable than in Marx's time for example). Blaming, dehumanising and scapegoating minority groups (the 1%, bankers, etc) to expiate our sins does nothing to help our society become more fair, quite the reverse.
The last century under moderated capitalism has seen much progress in conditions of work in the western world, and even recently in the developing world, and this in spite of the selfishness inherent in capitalism which you would think would tend to ever-increasing centralisation of power and wealth if left unchecked - I find that an interesting contradiction.
If people want to debate redistribution, what fair means, how to moderate capitalism or replace it and how to make our societies more fair that's (in my view) a useful debate, but diatribes about a shadowy conspiracy of a 1% elite spanning centuries are not productive, because they're not going to make people face with sober senses their real conditions of life, and their relations with others in society.
