If improvement on researches , education happens globally US won't be the only country that would come up with new ways of doing things...
for example look at africa, currenly lots of charity is done to increase the life standers of people in Africa. when their primery concerns like water and health are taken care of, quality of education can be increased drastically, an educated society will be able to take care of themselves.. they wouldn't have to be depend on welfare after reaching that stage...
