Not sure I understand your point. These are all state tier achievements. If anything it's where the state is either disorganized, broke, utterly corrupt, or all that make it difficult to achieve those goals in the first place.

You are saying we shouldn't have to pay taxes so the state can plan and execute vaccine campaigns and offer chronic disease treatment without cost to the patients that need it?

This is the case in Brazil (for instance http://en.wikipedia.org/wiki/HIV/AIDS_in_Brazil) and I happily pay my due to make it happen.

Not all tax money is actually put to good use, but the greater part is and I certainly wouldn't advocate against that.

Of course some countries have weird priorities IMO (yes, US) and may not share this view.

Yes dodgy's point is probably that this tax money sent to US govt will not result in such achievements like medicine in developing countries.
