The time has come--if it is not already too late--to settle upon the best available idea and advocate for its implementation: "Calling on the Writers on Medium."
My candidate is the establishment of a 'democratically distributed income', i.e., an income a person could actually live on for which any adult citizen could become eligible. It can be accomplished in any nation with a single legislative Act. As designed, it would make the economy self-regulating while eliminating unemployment and poverty and increasing sustainability. The same process can be used to fund fund all government, eliminating taxes/public debt. Otherwise, there is little to recommend it.
If anyone knows of a better idea that is as doable, please do apprise me of it.
