I think there's a little more foundation to it that just "Occam said it". I think the point is that the simplest theory is a) a lower bound and b) most valuably falsifiable. Take a theory, add a bit about a Unicorn. or a Dragon. Now you have a more complicated theory. You can arbitrarily contrive a more complicated solution. But the simplest? You've found a local minima. And because it's more stable you can compare it to competing theories without trivial refutation. see: the 3-5 theories of dark matter.
