I was sure it was "healcare SPENDING" ... in context, it WAS money spent on health care being a direct link to expectancy.
And you are still cowardly avoiding an answer; you attack me because there is absolutely NOTHING you can do to counter my argument. "oh boohoo the evil man is mean and disrespectful of us"
On the other hand, yes I off handedly insulted people who completely ignore facts to concoct their imaginary little world by calling them stupid. But I only do so after presenting irrefutable evidence.
I'm avoiding an answer, and there's NOTHING I can do to counter your argument?
Well seeing how you said that people were idiots if they thought healthcare was linked to life expectancy, countering that is countering your argument, and is providing an answer. It's not my fault if you made a mistake and chose to state something that wasn't fully reflective of your views, and your manner of confessing to such a mistake leaves a lot to be desired!
Anyway now that you seem to agree that healthcare is linked to life expectancy, we can move on to the next step in the logic chain:
The more you spend on healthcare, the better the effect on life expectancy should be, ceteris paribus.
Now are people idiots for thinking that? If not, we can move on to step 3! 
what's wrong about my alternative to Obama's healthcare system and why Obama's healthcare plan is morally superior to my proposal?
Ignoring the morals and focusing more on the pragmatic side, it would be more difficult to administer healthcare to a different country, which would increase the scope for waste, inefficiencies and/or corruption. In addition healthcare provided within your own country means that you (as a government) receive the benefits. That is, if the healthcare helps make people live longer, and/or keep them productive (i.e. not sick), then that means they can produce more, so the economy benefits, and tax revenues increase.
Of course I'd be surprised if these factors combined were enough to bring the 'life saving' close to a parity, and would expect that you could still achieve more 'years of saved life' by spending it in Africa than in the US, but it wouldn't be beyond the realms of possibility.
In terms of the moral side, every developed country I know of has an inherant moral judgement that the lives of their citizens are worth more than the lives of non-citizens, and this can most easily be seen by their immigration policy. Unless they have an 'open borders' policy where anyone no matter where they are can enter the country (with basic exceptions such as security risks/criminals etc.) then in my mind there is an implicit judgement that their citizens lives are worth more than outsiders (although there could be other factors/reasons that might affect this).
