This then that makes the argument very hard to respond to.
"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.
Would anyone take literally the claim that it is impossible to attain a billion dollars without 'doing something bad' or 'cheating'? Someone with $100 billion, who wanted to disprove it, could do so in five minutes, by cutting a $1 billion bonus check to his nanny.
