Economics (rant thread)

[Froge]

Can someone justify to me why this subject is useful?

I recently finished my economics exam and I'm glad that I never have to take it again. It was an elective I took because I heard about how useful it was, but on the whole I found the subject mind-numbingly boring and very inapplicable. The course was on microeconomics and included topics opportunity cost, demand and supply, elasticity, household utility, and theory of firms.

Why does economics exist?
