I don't think I could be any clearer that I am (1) talking about Americans with private health insurance and (2) not making a normative judgement about which system is better, but rather a positive claim about the political challenge of changing the system (its large group of stakeholders who are better off under it).
Oh I'm clear about the demographic you are trying to discuss, my point was I'm not sure this all stemmed from a discussion about that specific demographic. It started at "people in US", then went to "most", then by the time you got involved in the thread you were defending a statement about people with private health insurance.
I could have made this comment at the level where it went off the rails, but I thought making it at the leaf level would help everyone involved see the deviation between what was said and what was being argued.
