A good article, Stephen, and I like that you are looking for ways to make society better for all.
I am trained in economics and I have dabbled quite a bit in philosophy (and science) to know about ideas.
Yet when I take one quick look at the happy nations in the world, then we can already see where the crux of the matter lies. It is not with property per se.
It's the voting system.
It is more complex than just this term, and the voting system in the USA can only get changed today at the State and the local levels.
However, that should already suffice to make enormous steps forward in the distribution of our socieconomic wealth.
The Scandinavian countries rank high and dry on the list of happy nations, and what they have that we do not is two-fold.
1/ They have one House and one House only. We have Presidency, Senate and House, and when we vote three times, we can undermine ourselves in a good number of ways. The more things change, the more they stay the same.
2/ They vote proportionally.
The worst voting system in the world is winner-take-all. Talk about uneven distribution and the voting booth is the first place where the haves are separated from the have-nots.
The majority supporting a decision in Sweden is supported by the majority of the voters.
The majority supporting a decision in the USA is supported by 30% of the voters. The remaining 20% got eliminated in the voting booth.
That is why the GINI numbers for the USA are not that good.
Our voting system is an elitist voting system; it supports the elite (be it left or right, but definitively not a system for all voters).
Look for the happy nations. Figure out why they are the happiest in the world (and even have the happiest immigrants in the world in them).
Then, come talk to me. We can change the United States, Founding Fathers improved, today.
