I didn't mean to suggest that every person 'running things' was accurately described by each label. I meant "idiots, scumbags and criminals" as a domain.
I wouldn't even rule out that an exception or two might not fit into any of those labels. I just don't think they're statistically significant.
I just mean that I don't see that he was right by definition. That would mean that the world is run by idiots by definition, which is obviously false (that fact, if it is a fact, doesn't follow from the definitions of any of those words).
Maybe so, but it's certainly not run by idiots "by definition", if you have the normal meaning of the phrase in mind.
