I didn't really suggest that the US Government spends money on healthcare, I was merely quoting the article: "Health care consumes 18% of GDP in America" Please note that the wording implies that 18% of GDP is spent on health care overall not that the US Government is spending all that money out of its pocket directly on yearly budgets. The way I understand it is that it includes both money spent by public and private actors for all health related service. I see this type of stat a warning that something might be dysfunctional within the system, and it's the government's job to get to the bottom of it.
