It often goes unsaid, but America, on a cultural and political level, is really ideologically fixated on a distinction between working and non-working individuals, and, in a far deeper sense, whether an individual "deserves" healthcare or not. This makes access to healthcare intricately connected to class, wealth, and income, in America. That's why access to healthcare is seen as a product in and of itself. You can either afford it ("you've earned it"), or you go into debt for it ("you have to earn it"), or you simply have no expectation of ever paying for it ("you cheated the system").
The entire conversation is often dominated by these ideas in a way that often makes talking about healthcare with Americans baffling to people that come from many single-payer or universal systems.
