My studies have taught me that making the existing economy more just, via a "democratically distributed income," would have the unanticipated benefit of making the economy more sustainable--without imposing limits on income or wealth: "For Crying Out Loud, ACCEPT That A SOLUTION Actually EXISTS" (a "3 min read"--including options for further reading--here in Medium). Total output would be governed, passively but effectively, by demographics; it would not need to be maximized so as to maximize employment, income, and tax revenues.

That income could be extended further (with still no limits on income or wealth) and of itself all but assure sustainability: "A Fully Just Economy."
