I have a degree in economics, but I confess I really didn't understand the whole thing until much later in life, when I was able to look at it through the lens of e.g. video game design. Which is to say, there are real consequences and real effects of actions -- but the economy still isn't something like "nature" or "scientific" despite what many would have you believe. It's much more like a designed game who's rules can be tweaked, sometimes arbitrary, etc.
