First of all, he's generalizing from an anecdote of one, which is intellectually lazy and morally reckless, when it results in a negative characterization of a large set of diverse individuals who share the trait of being free market capitalists.
Second, in the quote, he refers to "unregulated free market capitalism" not just "capitalists", and describes what it, as a political and economic doctrine, allows, and his description is unambiguously false.
It's a hit job. It's intellectually dishonest and not fair to the target.
>>He’s discussing a biography after all.
Yes, but in that excerpt, he clearly makes a claim about "unregulated free market capitalism". An individual in his position, writing for a highly reputed publication, has a moral and professional responsibility to not make false claims, even as a side-note in a piece about a different subject from the claim.
