You reinforced my point in fact: "It would be better to restructure this sector and make it efficient."US medical system sucks, take it from someone who is living in US and experiencing it first hand, yes they have good services and doctors but they will rip every penny off your skin, do you know that just make a 911 call and order an ambulance can cost you up to 1500$?
US spends a lot on the military because they have to and they have no choice, without Powerful military they lose their SUPER POWER Status, and that influence they enjoy over weak countries.
They spend so much in the health domain (Medicare + Health), and still have a health system that is a lot to be desired. I am not sure how Americans are putting up with this rubbish.
