The for profit government subsidized system in unsustainable. The insurance companies will keep raising rates to meet their profit goals, subsidies will have to increase to maintain the status quo but eventually the whole thing will collapse.
It was the original criticism of capitalism, perpetual growth of profit is impossible. Although Adam Smith thought that we would ultimately reach a stationary state where everyone would be happy. I guess he didn't foresee the Oligarch Class rebuilding feudalism.
