The market approach would be easier with the CCP social credit scores and central bank digital currencies mandated, but I don’t think that is what he is talking about. He imagines a free market, not the planned dictatorship of the big banking cartel. I have a credit union and pay in cash mostly but some businesses will not take cash already and others shame you if you try… The Green New Deal scam is probably a concession he will have to make in order gain allies if he has any hopes of actually winning.
As Dark Journalist pointed out, make huge corporations and the military pay for the clean up as they are the biggest polluters.
If he makes a Concession, he makes a Devil’s bargain… If he’s for real and means to do some good…He gets “Clinton-ed”… Our problem, I believe,- is the vain hope in a parental Archetype that’ll clean up this mess…
