I don't know what the exact unutterable "dangerous" solution you have in mind, but I can assure you, that's not it. The concept of inequality is bred into the human psyche (our hardware or software), you cannot get rid of simplistic social constructs such as communism, etc. Even if technology advances to the level of creating robots to do all menial tasks, our concepts and need for inequality will not go away (for a…
>The concept of inequality is bred into the human psyche If it's inherent then why are there examples of societies which lack it?
One can say that's not what this discussion is about, i.e. it's the potential for equality, the right to be equal rather than the radical definition above, but then the discussion becomes muddled, how to measure inequality, economically (e.g. the Gini index), by asking people, etc. "Inequality" then becomes a very complicated word like "democracy" or "justice".
I think it's interesting to draw a comparison with democracy: "true" democracy, i.e. radical democracy, is likewise impossible to maintain. The closest form in Athens degenerated to tyranny many times. And probably Athens was the largest collection of people where such pure democracy is feasible, i.e. it cannot be scaled up to a whole country. Judging from the lack of other examples in human history, one can see that the order of things in Athens was not the natural state of society.
So, I maintain that pure forms "liberté, égalité, fraternité" are not practical and cannot be achieved.
Now, one can argue back, saying "Yeah, yeah, we know that, but surely you can rank countries on how much they have achieved these, e.g. surely no one would debate that the US is more democratic than Saudi Arabia." This, of course, is true, but (i) means that we should leave behind "a brotherhood of men, and no possession, too" crap behind and (ii) leads us back to the question of measuring inequality.
