I doubt the people in this article are middle class. Only one income is mentioned, but $40k for a family of three is below the definition of middle class for most of the USA. Lots of people who think they are middle class are really poor.
We need a Federal expansion of Medicaid to be available to everyone with pricing based on income. Once wealthier people start moving over to it, the private insurance racket will collapse. I'd move over in a heartbeat, even if the costs were higher because the plans I have available to me are garbage and my family can't all see the same doctors because my insurance won't cover my partner's and vice-versa.
