The financial economic system of a society is inseparable from its political and belief systems. Human society is a very complex system in which everything intersects with everything else. Because of this, the financial economic system of a society has to be designed to help a society achieve its long-term goals based on its fundamental beliefs.
Since our belief is that society has a long-term goal and it is the job of every single member of society to contribute according to their natural talent to achieving that goal, it doesn't make much sense for people to have better material lives simply because they are lucky to have the natural ability to obtain skills deemed important by the 'free market'. A medical doctor shouldn't necessarily live a better material life just because he got lucky with superior natural memorization or intellectual ability than a plumber for example.
Financial reward to individuals for contribution to society should be based on effort made in contribution to long-term societal goals according to their baseline natural ability, not simply absolute ability as randomly awarded by nature. This helps:
i. balance what might be natural unfairness in the distribution of ability, which currently allows people with a higher natural ability (due to no inherent worthiness on their own part) to have better material lives.
ii. remove lopsidedness to the distribution of talent in the complex system of society based on what career earns what. Exceptional talent can work in any industry no matter its immediate 'value' (what the existing free market measures) to society.
iii. clarify to everyone what matters in an economic system is an abundance of production which lowers the prices of goods and services, not individual attempt to improve individual income by working a 'better' job.
Because everything is made from naturally-existing resources, the only thing that matters is the level of scarcity or abundance of specific resources. The price of a good/service is a measure of the abundance or scarcity of that good or service.
Financial incentives/reward for fulfilling 'market opportunities' should not exist at all. That means no private ownership of capital like land or financial assets. The state owns everything because it thinks and plans things very long-term.
People who want to do exceptional work that improves society will be provided resources by the state but will be unable to get wealthy because of their work. Everyone simply works at a level commensurate with their natural talent.
This doesn't kill the existence of 'markets' as an interaction between demand and supply to determine price. Everything around that still works exactly the same because it is apparently what is best.
What else changes? Everything logically downstream of the fundamental belief.
All of taxation for example. Why do you need taxation if everything comes from natural resources owned by the state and there is no private ownership of capital? You don't. Taxes are fake, as is almost everything else around how the financial economy currently runs, like financial debt.
Why do you need financial debt? There is no private ownership capital, remember? You therefore do not need need debt to finance any business interests. Have a cool idea you'd like to pursue? There are people in charge of managing the state's resources who will send some of those resources your way if you are convincing enough. And there will be no extra financial reward from those pursuits. You get rewarded based on your effort as commensurate with your natural talent.
Personal financial debt ceases to exist too. Anyone who needs personal debt as a result of financial mismanagement actually gets penalized for it. People who genuinely need outside help for a legitimate reason get freebies from the state.
Personal financial debt is psychologically ruinous and thus evil. Ending it is saving everyone from a lot of trouble.
Basically, everything about how the current financial economy works is unrigorous and fake. You can simply throw it all in the bin.
