AFAICT many private schools are worse than public schools. Parents put kids into private schools so that they get good grades and extra-curriculars to let them get into the good universities. So that's what private schools sell -- good grades. It's less important that they have the education that the good grades imply.

I have no doubt schools like that exist, but in every location I’ve lived and interacted with parents the private school educations they sent their kids to were no question a cut above.

I think this idea that private schools are no better are even worse is a wishful thinking narrative. Private schools, especially the more expensive ones, naturally select for parents who are more involved. More involved parents are highly correlated with better student outcomes. That alone means private schools are correlated with better outcomes. It honestly doesn’t really matter if it’s cause and effect or correlation, parents send their kids to private schools because they want them in the mix with other students selected into the higher performing environment.

They do perform better on average

>The average private school mean reading score was 14.7 points higher than the average public school mean reading score, corresponding to an effect size of .41 (the ratio of the absolute value of the estimated difference to the standard deviation of the NAEP fourth-grade reading score distribution). After adjusting for selected student characteristics, the difference in means was near zero and not significant.

For math:

>The average private school mean mathematics score was 7.8 points higher than the average public school mean mathematics score, corresponding to an effect size of .29. After adjusting for selected student characteristics, the difference in means was -4.5 and significantly different from zero. (Note that a negative difference implies that the average school mean was higher for public schools.)

In the context of the specific discussion here, it doesn't really matter that the effect goes away when controling for selected student characteristics. First off this was from 2006, we would have to see if any of that has changed. The 2024 numbers are here[1]. But in any case they are not worse than public schools, although they may be no better or slightly worse than a public school in a rich neighborhood or similar.

Considering private schools cost tens of thousands of dollars and get to choose who they admit, as good (in reading) and worse (in math) than schools with similar demographics seems pretty damning, doesn't it?

Damning for who? Education is just one reason parents choose public schools for their children. Depending on the school (eg. Catholic schools) it may be the last thing they care about. Also you should look at the cost per pupil for public schools. It is very high in many states, with the average being $18,000 per student in 2021.[0]
