Quick answer
Both men end up wearing something. One inherits a condition by default; the other is crowned with what he acquired.

The verbs carry the contrast. "Inherit" is passive and unearned, which is exactly right for the simple person who has done nothing in particular and therefore receives folly by default, the way an untended field receives weeds. "Crowned" is public and deliberate. What the pairing says is that folly requires no effort and knowledge does, and that the difference between the two men is not that one was clever but that one moved.
