The affordable care act doubled most people's insurance over night (This happened to me and almost everyone I know). Nobody wants to mention this, because it makes their side look bad. Until we can admit where there are problems, there will never be a solution.
Market forces naturally create low rates for those who don't need insurance and unaffordable rates for those who do. But over time, everyone gravitates from the former to the latter.
The "free market" does not offer a practical solution to every problem. Tariffs are an open admission of this basic fact.
