A developed country is not where even the poor have cars, it's where even the rich use public transport - a quote attributed to many including LKY.
Extrapolating this to the current argument (disclaimer: not read the article), if the same system is thrust onto the rich and poor alike, it should get better over a period of time, no?
This is a complicated question, thoughts welcome.
The student body generally excels. A graduating class of 120 students might have a dozen who score 30+ on the ACT. And, of course, there is perhaps an equal number who fail to graduate.
They all go to the same school, but I wouldn't say "the same system is thrust onto the rich and poor alike." The most important system in the education of a child is not within the walls of a school. It is within the walls of their home.
It is simply true that a certain level of affluence is necessary to provide a stable learning environment * in the home *. Affluence does not guarantee that stability, but it increases the odds so dramatically that its affect should not be ignored.
(I say that as a husband to a public school teacher, son of a public school teacher, and father of children attending public school.)
and beyond that, isn't the whole point of GP's comment that the idealistic rich people are trying to / would like to leave their children in public schools? what's idealistic about sending your kids to private school instead? seems like the exact opposite to me.
so other than "pay" not making any sense, "idealism" not making sense, and randomly swapping whose (not "who's") idealism is being paid for, your reply makes perfect sense.
like, when people make comments like this, do they think that they are saying anything in particular, or is it just about the words sounding good in a certain order, like music lyrics? it's like some sort of pathos DDoS. but, hey: at least "your heart's in the right place", right?
