I agree that we need a big change to the economic system, but my studies have taught me that all we really need is a better way of supplying the existing economy with money: “For Crying Out Loud, Accept That A Solution Actually Exists" (a "3 min read" — with options for further reading — here in Medium).

The basic idea is a “democratically distributed income” that would be paid to eligible citizens (not all citizens, though any citizen could become eligible for it — which is what makes it “democratically distributed”). The money for that income would be created as needed. The total of the income would form the supply of money for the economy. The outcomes for society would be astonishing: no unemployment, poverty, taxes, or public debt and increased sustainability.

This is not something I came up with this morning. It is a full developed paradigm.
