Not sure where the author is living but I work long hours, have to run home and pick up kids who have been waiting after practice for me, fix food as quick as possible because they are all starving…My kids attend public schools and they do their homework on their own when they get home. They have lockers and smelly socks and messy rooms and there are clothes in the dryer that have not been folded but at least those do not smell (most of the time). Our lives are not perfect and my kids are not Einsteins or college athletes. This article is rather elitist and definitely insulting. There are good and bad parents in every tax bracket. I do think it helps when you have the means to get tutors if needed or prep tests before the ACT or SAT. But I think this guy needs to get out in middle America and see real people. Oh, I forgot, he probably detests “fly-over states” and would not be caught dead at a diner that serves fried catfish. 
Does he have kids? Has he ever lived anywhere but NYC? Where did he go to school? does he have any friends? lol
