I majored CS and with minors in Math and Econ. The economics minor was one of the better decisions I made in college and sometimes I think I use it more than the CS stuff. For example, things like opportunity cost I use almost every day, while it's rare I analyze the "big O" run time of code I'm writing. From what I saw of the higher level econ classes, you're completely correct. For the most part they're not learning much new stuff, they're learning the same stuff in more detail and investigating why. It's interesting, but has limited applicability to real life. The low level courses are also interesting but have real life applications all over the place.
