I appreciate the critique of "bright green" in the article, but it is hard to avoid the impression that nothing short of moving back into caves would be good enough for this author.
As it happens, I have developed a truly revolutionary paradigm. It might be too late even for it, but my position is that it's never too late to do better.
The paradigm does provide for possibly paying a 'livable' income to households (based on current incomes and prices in whatever nation might adopt the paradigm)--without involving taxes/public debt in any way. I acknowledge that developing possible parameters of such a payment is not something on which I have expended much time or effort, but presumably any approach to providing such a payment would be very culturally, if not nationally specific, anyway. Even without that option, demographics would govern total output--and everyone employed in any business or government could possibly receive the same pay (with or without differentiated supplemental 'benefits').
If curious: "A Most Beneficial Economic Change" is a "2 min read" here in Medium with links to article about the paradigm from different angles within economics (with, for the benefit of 'guest readers', nothing I publish here behind the paywall).
