"No I didn't mean this [virtuous example]. I meant the vast majority of [unnamed nefarious actors] which I don't need to elaborate about as their existence is obvious."
Once you say it's just hyperbole and you don't mean it literally, then the only way to prove it is a statistical argument.
"The overwhelmingly share of company founders and companies are bad and don't earn their money." is a big claim that requires more than vibes.
Whether my comments constitute a motte-and-bailey depends on whether a reasonable person would assume the "impossible to earn a billion dollars" statement to be hyperbole.
