I get what you're implying, but I want to point out that healthcare is not "directly tied to your enthusiasm." I'm sure somebody can post their anecdote about being fired for not having enough pep in their step at work, but enthusiasm for the company mission is not a typical requirement for employment. Furthermore, despite the pervasive online meme to the contrary, the US does have a substantial social safety net — we devote more of our GDP to public social spending¹ than Canada or Australia. It's completely fair to say that the outcomes can vary, but it's not fair to say that Americans are by and large left rudderless without help from the state if they lose their job.
