Politicans and people like them, who talks a lot and doesn’t really affected by their actions. Their three flaws:
We saw that interventionistas don’t learn because they are not the victims of their mistakes.
Honor implies that there are some actions you would categorically never do, regardless of the material rewards.
There are two types of “talking one’s book.” One consists of buying a stock because you like it, then commenting on it (and disclosing such ownership)—the most reliable advocate for a product is its user.fn6 Another is buying a stock so you can advertise the qualities of the company, then selling it, benefiting from the trumpeting—this is called market manipulation, and it is certainly a conflict of interest.
Intellectual and ethical freedom requires the absence of the skin of others in one’s game, which is why the free are so rare. I cannot possibly imagine the activist Ralph Nader, when he was the target of large motor companies, raising a family with 2 kids and a dog.
Aristotle, in his Rhetoric, postulated that envy is something you are more likely to encounter in your own kin: lower classes are more likely to experience envy toward their cousins or the middle class than toward the very rich. And the expression Nobody is a prophet in his own land, making envy a geographical thing (mistakenly thought to originate with Jesus), originates from that passage in the Rhetoric. Aristotle himself was building on Hesiod: cobbler envies cobbler, carpenter envies carpenter. Later, Jean de La Bruyère wrote that jealousy is to be found within the same art, talent, and condition.
