I do have a (fully developed) alternative to offer. It is a way of transforming the societal outcomes associated with the existing economy (any existing economy), not replacing it. It can absolutely, positively make the economy fully self-regulating while eliminating unemployment, poverty, taxes, and public debt and increasing sustainability--all without imposing any limit on income/wealth. The same paradigm could add eliminating exploitation to that list of benefits--without taking anything off it: "Permanent 'Quantitative Easing'" (in Medium).
