Yep, known as Bloom's Two Sigma Problem[1]. Like most hard problems we know the solution, but lack the appetite to implement.

The study picked an artificial and useless proxy.
What did tutored students go on to do? Were they over represented in Nobel Prizes, hedge fund billionaires, heads of state?
Or did they do well on a meaningless test and then forget all about whatever they “learned” just like everyone else?
The entire field is absolutely littered with this problem. Everyone is targeting cholesterol and not all cause mortality.
What evidence would change your mind?
Hey Bloom’s 2 sigma problem. So far, (nearly) all conversations about education on HN I’ve seen, have had a naturally point at which Bloom’s 2s should be introduced.
Humanity is now preparing students with a 20 year time horizon, while tech changes much faster. If this was agriculture, the industry would be doomed by that horizon mismatch.
We really need more teachers, if we want the median citizen to be better off.
