The problem in USA is that in grade school teachers do not seem to nurture love of things that individual students are good at. Theoretically people should pursue careers for which they're gifted. Military career is very challenging as it requires love of country, sacrifice, perseverance and most importantly realization that person may get killed or have to kill another. This is not for everyone. Lets see.... Well, those who are not particularly gifted should become maybe religious preachers?
