First, thanks for such a cogent analysis.

I do agree that even if it were desirable we cannot recreate any past set of circumstances. I also agree that, short of a radical razing of the extant institutional structure, our options are limited by present circumstances.

I did, though, stumble upon a way to at least rid society of unemployment and poverty within the context of the existing institutional arrangements. It should be politically feasible because it does not impose any cost on employers, does not involve redistributing anything, does not impose any limit on income/wealth,, and is not dependent on taxes/public debt.

I know it sounds 'too good to be true', but those outcomes, within those strictures, are absolutely, positively guaranteed. They are the result of a single change to the existing institutional construct, not a set of hoped-for outcomes stemming either from an abstract economic model based on hypothetical assumptions or from a radical restructuring of society. That does mean that those outcomes can be achieved with a single legislative Act.

If curious: "Same Economy, Way Better Outcomes for Society;" given the totality of the circumstances we face, it might be necessary to take that concept to it furthest possible application: "To Preserve What We Have, What We Have Must Be Enough" (both here in Medium, but not behind the paywall).
