Columnist David Winston’s denunciation of the plans of prominent Democratic presidential candidates (“The Green New Deal debacle” Opinion, 4 / 7) condemns these plans as unrealistic but he conspicuously fails to attack them in terms of the ultimate policy goals and aspirations that they are aimed at. He attacks Medicare-for-all plans as socialism and unrealistic but this ignores the fact that such system’s have been and continue to be successfully functioning in at least 30 democracies worldwide for decades. This is not, as Mr Winston evasively portrays it, a left-right or socialism versus capitalism issue. It is a straightforward smart business proposition that will produce better health care for lower overall cost to most Americans with a humanitarian goal of universal coverage. What’s unrealistic about that?
