True . . . but the overwhelming majority worship their own brand! In other words, you want to get hired by a University of Alabama graduate? Well, you’d better hope that’s where you graduated from too, if you want a leg up over other candidates. An Ivy degree matters if you want to work on Wall Street. But if that’s not your goal, then any other college will serve you just as well.
This doesn’t even merit a response. If you’re a freshman in high school, you ought to be able to do simple math - add up the number of Ivy applications in any year, and compare that to the number of high school graduates during the same year. Keep it simple, stick to U.S. graduates only.
