I believe the focus should be more on the political system rather than the economic system. The state itself and how it functions.
The best political system I have seen in practice is what they had in Libya prior to the NATO invasion.
Direct democracy.
No politicians, no political parties.
Public ownership of natural resources.
They, the Libyan people, under Gaddafi's guidance lifted themselves out of poverty and became prosperous, living lives we in the west could only dream of.
Want to be a doctor? Be a doctor, the people own the university, the fee is the value you add back to society with your work.
Want to be a farmer? Here is some land and seeds, here is some livestock, go and be a farmer.
You just got married? Here is a home ror you to raise your children.
Where does all the money to pay for it come from? Public ownership of natural resources, Libya had oil. Every citizen was treated like a shareholder.
How did Libya make it work?
A small population with a homogeneous society with shared values definitely made it easier. 5 million people is not a large population.
How could we make it work in larger countries? I believe blockchain might be able to facilitate it.
Instead of voting for politicians to make decisions on our behalf, we can collectively make those decisions ourselves.
That's what direct democracy is.
And I believe with Bitcoin as our money, and direct democracy as our political system, that a better economic system will naturally evolve to suit society.
Whatever happens, neo liberal capitalism will die, its the least sustainable economic system the world has ever seen, money based on debt. It will kill itself.
Whether we regress to an older capitalist system or progress into a new economic system time will tell.
We may actually need to regress back to pre 1971 capitalism before we can progress towards socialism or whatever the future holds.
