Thanks for your great comment. A couple of thoughts on the point you raise at the end.
First, it’s inevitable that with limited resources countries will likely have to expand gradually – as their economies grow – the list of health service needs they commit to satisfying. It’s a tough decision, of course, but a necessary one; even very rich countries don’t promise absolutely everything. I suspect a consensus will likely emerge on what populations might reasonably expect depending on their country’s GDP per capita.
