I agree. There is also a macro-level solution for sustainability available, one that would not change the basic nature of the existing economy: "For Crying Out Loud, ACCEPT That A SOLUTION Actually EXISTS" (a "3 min read"--including options for further reading--here in Medium). [Apparently links are disabled in this new Response platform.] In it total output would be governed, passively but effectively, by demographics--with no unemployment or poverty at any level of output (but still no limit on income/wealth).
