Proponents of "Medicare for All" tout it as a ready-to-go answer to the shortcomings of ACA. But they seem to have a lot of misconceptions about Medicare. The worst of these, in my view, is the idea that Medicare takes for-profit insurance companies out of the equation. On the contrary, it secures their position, and their profits. Medicare is essentially a group insurance plan, purchased for you by the federal government. It's not much different than a group plan purchased by an employer for their employees. And it's still still sold by private, for-profit insurance companies - often the very same insurance companies who have been screwing us for the last fifty years. These companies are still responsible for approving, and denying claims, and they are still driven by the same profit motive. It's just frustrating to see so many people kidding themselves, thinking that Medicare for All would somehow steer around the insurance companies, when it reality - just like ACA - it would simply herd us all into their clutches.
