Thanks for your comment.
Let me try to clarify a couple of common misconceptions.
First, UHC is a policy goal, albeit an intermediate goal. (Ultimately we’re after better health (for everyone) and ensuring people have enough money left over after any health spending to buy other things they need and want.) Committing to the (intermediate) goal of UHC doesn’t say anything about the institutional arrangements to achieve this goal. In fact what’s really interesting is that countries are not using old health financing and delivery arrangements to pursue UHC for precisely the reasons you give. UHC is triggering a wholesale rethink about how health care is best financed and delivered. See my blog post on health reform in Asia from this time last year and the 22 UHC case studies that the World Bank recently published.
Second, as countries grow they can afford to commit to satisfying more and more health service needs. The “universal” bit of UHC is about who is covered, not what is covered. As countries grow, they’ll be able to cover more and more health needs; after some point, coverage may become comprehensive as well as universal. UHC doesn’t eliminate resource constraints and the need to limit what’s covered.
