When this concept began emerging many years ago, I worked with physicians, and their concern was whether they would get paid enough. They had grown accustomed to very comfortable, often affluent lifestyles. So what you are describing is an evolution of their thinking. This was just starting when I left the physician environment. My 2 cents. And to be clear, I work hard in favor of Improved and Expanded Medicare for All. (Medicare needs some tweaking for it to be universal). Appreciate your article nevertheless!
