Economic Equality Impossible

It is utterly impossible to have economic equality on any scale.
That’s not because of the laws of economics, but because of the fallen nature of mankind. It is not possible for men to think their way to solutions which would work. Every measure ever tried under any political and economic system always produces unintended consequences which constitute failure. That is, such policies invariably create new problems which make things worse.
The answer, of course, is not libertarian government with open markets. This is also going to guarantee injustice, because it simply allows the worst of human greed to run untrammeled over the bodies of those who are not part of the elite. There is no system of government devised by man which can prevent the rise of an elite who then abuse the rest.
On the other hand, there is a plan of government and economics which works as well as can be expected, but it wasn’t devised by human minds. It is built into human nature. It’s fundamental the Laws of Noah: The extended family kin must restrain their own family members. There is no other social structure which makes genuine restraint possible, which offers the single greatest degree of shared prosperity with minimal exclusions. When a family shares the wealth, the mere existence of normal familial bonds minimizes injustice to the degree possible with fallen mankind.
Nothing has ever worked better; nothing possibly could work better.
The last people on earth who are eager to oppress are your own family. Yes, we do have a cultural bias in the West which finds families going to war and defending their own against other families. This is human nature, but mad worse by the pagan nature of Western civilization. Ancient Near Eastern cultures were much more aware of the consequences of allowing your family to intrude into the lives of others. They were quick to restrain their own, even to the point of shedding the blood of their own to restore justice. It was a point of pride to permit no harm to other families, not to mention a survival concern, since the others could gang up on you. No one in the East wanted the feuding so common in the West.
Fundamental to the Laws of Noah was the requirement families restrain their own in that way. No one else has the standing to do that, in God’s eyes. We realize families members are loathe to get involved and restrain their own. Yet, no one on this earth has any business poking around in your life except those bound to you by blood and/or covenant. No one else will be so restrained, will offer you as much freedom as possible within the boundaries of common welfare. Whatever flaws you may perceive in the patriarchal tribal system, everything else is far worse.
The problem with economics is the same problem with human government in the first place, and the whole human race seems determined to avoid the only real answer.
