OK, using your resources to impose on people with your pop philosophy is an unambiguously bad thing, this I agree with. But I have a problem with this article and the initial post, and it's a problem common to most take-downs of the ultra-rich. Usually, they aren't actually critiques of the ultra-rich, they're critiques of the talentless ultra-rich. That's a problem, because it takes a structural problem and then makes it personal—de Botton, Solomon, St Aubyn, Salles as egregious examples, as Marie Antoinettes.
There's an implicit argument here, once you've removed the tongue from the cheek and put the words back in: people shouldn't be so rich if they're talentless. They didn't deserve it, in other words. And the inverse of this argument gets floated around a lot in the USA in the cases of the murder of people of color by police; . For example, Michael Brown "was no angel" (the NYT), as if angels have a greater right to life—this is shitty, sneaky advocacy for capital punishment by degrees, the deprivation of life by some moral standard (and merit is a moral standard). In both cases the notion is that without providing social benefits they should be given no social protection. It's a kind of meritocratic idea.
OK I'm straying from the article, but I did want to say that we can't have stupid critiques of the concentration of wealth, they can be funny, they can be short, but they shouldn't reinforce meritocracy, which is a power structure with no just philosophical basis.
So I want to expand the discussion to a few other examples of people who inherited. Maya Lin, the architect and artist, niece of Lin Huiyin, leading architectural historian, essayist of early 20th century China. Felix Bernstein, a good critic and (good? I don't know poetry) poet who is child of Charles Bernstein, leading NY Language poet. Ai Weiwei, son of the poet laureate of New China, Ai Qing. Until our critique of the talentless super-rich is modulated to include cultural capital, it's a bad critique that does nothing but let off steam by scapegoating. The problem is inheritance, not talent. That includes cultural inheritance.
Edit: @b_taylor the pictures of Tarinan von Anhalt painting are amazing.
