Sustainability is the established watchword cum battle cry of 21st century world transforming progressives everywhere. Its most identifiable provenance was the 1992 UN conference which gave us the globalists’ plan for the future – Agenda 21. Today sustainability is continually evoked as the raison d’etre for stultifying public policies that constrict our activities and take our properties. However, any concerted attempt to discover a coherent meaning of sustainability yields definitions that are literally unusable in any serious exchanges between thinking people (e.g. see dictionary.com). In what follows I intend to set the matter straight so that well-meaning, intelligent RR readers may understand and use the notion of sustainability in reasoned discussions. In this context and as a Lucky Strike extra I present some newly, albeit belatedly, discovered information on the performance of single-payer healthcare systems that have become the holy grail of America’s ideology driven Left.
