You're right that they never said supply-and-demand was the only reason. However, E doesn't present an alternative reason in the first place. It just shows that not every high earner had a degree. However, that doesn't matter. This is normal in data sets, right? Sure, there are a few lucky or talented people who earn a lot without a degree. But that doesn't change our premise that ON AVERAGE, people with degrees earned more, and it does nothing to tell us WHY people with degrees earned more.
