While it may be true for a subset of posters here, the idea of just finding a new job if it doesn't suit you is not possible for most people. The majority of people need to be able to do something mildly productive and be able to live a happy life as a result. If your economic model is leaving this many people behind--or they even feel they're being left behind it's not a good model.
Everyday I find it harder to argue against things like medicare-for-all. Private healthcare only adds unneeded pressure to workers--heck even me sometimes. Even if it weren't cheaper which it should be[1], there is surely some value that soulless accountants could extract from lower stressors in the workplace.
