Every student who goes to college should have some idea of the history that stands behind his or her discipline. We are doomed to repeat what we do not know, as the saying goes. We should not naively be reinventing the wheel but study what humanity has done, good and bad, so we can make further choices.
The main goal of going to college is learning skills that will help you get a career that gets you a salary that you can use to provide for your family. History is one of the worst subjects to study. The only job you can get is a history teacher. Every year thousands of people graduate with history degrees everywhere. There aren't many history teacher positions.
