To make a bit of an analogy, I could have graduated with a computer science degree three years ago, but in my last semester, I decided I also wanted to get a physics degree. Now I'm going to grad school to get a master's, then PhD, is astrophysics. Eventually, I plan to be a research professor. I'll probably top out around $60-70K doing so. If I had graduated with my CS degree, I'd likely be making that much right now, and could have potentially made six figures at some point down the road. I chose this path because it's what I wanted to do, even though I know I'll likely be making ~50% of what I would with just a CS bachelor's. Bringing this back to making $200 million versus $100 million, some people would rather not take steroids because of personality, ethics, preference, you name it.
