Continuing from the last post. The beginning of the post at CT. The quote, linked from the source at The Atlantic:
Laura McKenna

Jonah, did you ask your French teacher about why you got that B on that assignment? At 5:00 p.m. today, you have an orthodontist appointment. We’ll pick up Thai food on the way home and then you’ll finish your English homework. Don’t forget to put a book cover on your essay. A book cover always bumps a grade up half a point. Your dad can check your math when he gets home. Do you want tofu in your green curry or chicken? Ian, do you want noodles?

Every once in a while, you step back from yourself as a parent and say, “Dude! Did I actually just say that? I used to be cool. Did some alien take over my brain and turn me into this Mom Machine?” No crab-faced alien can be blamed for transforming me from a slacker in a black dress into what I am today. According to sociologist Annette Lareau, I’m a product of my social class.

From an interview with G.A. Cohen [update: my transcription here]

I wrote a book called "If you're an Egalitarian How Come You're so Rich?" And the final chapter discusses fourteen reasons people give for not giving away their money when they're rich but they profess belief in equality, twelve of which are, well, rubbish. I think there are two reasonable answers that a person who doesn't give too much of it away can give and one of them has to do with the burden of depressing yourself below the level of your peer group with whom you're shared a certain way of life, and in particular, depriving your children of things that the children around them favor. And also, and slightly separately, the transition from being wealthy to being not wealthy at all can be extremely burdensome and the person who has tasted wealth will suffer more typically from lack of it than someone who's had quote unquote the good fortune never to be wealthy and therefore has built up the character and the orientation that can cope well with it.

The Times: Affluent, Born Abroad and Choosing New York’s Public Schools

Miriam and Christian Rengier, a German couple moving to New York, visited some private elementary schools in Manhattan last spring in search of a place for their son. They immediately noticed the absence of ethnic diversity, and the chauffeurs ferrying children to the door.
And then, at one school, their guide showed them the cafeteria.
“The kids were able to choose between seven different lunches: sushi and macrobiotics and whatever,” Ms. Rengier recalled. “And I said, ‘What if I don’t want my son to choose from seven different lunches?’ And she looked at me like I was an idiot.”
For the Rengiers, the decision was clear: Their son would go to public school.
“It was not the question if we could afford it or not,” said Ms. Rengier, whose husband was transferred to the city because of his job as a lawyer and tax consultant. “It was a question of whether it was real life or not.”

McKenna: "Don’t forget to put a book cover on your essay. A book cover always bumps a grade up half a point."

Cohen: "...the burden of depressing yourself below the level of your peer group with whom you're shared a certain way of life, and in particular, depriving your children of things that the children around them favor."

Rengier: “It was a question of whether it was real life or not.”

The desire to have your children learn from their own experience of the world.

Everyone is a product of their social class. The Rengiers come off well; no one else does. McKenna is just vulgar, but I'd forgotten how close Cohen comes to sleaze.
