The article you linked is utter garbage though. Half of it is nonses not backed up by anything “So a higher suicide rate actually increases test scores.

Would you say this makes other countries superior to the United States? Heck no! In fact, just the opposite. I certainly wouldn’t wish more underperforming U.S. students were ending their lives so we could do better on international tests. Nor would I wish that more premature babies died to improve our international standing.” I mean it actually tries to blame othe countries suicide rates on them doing better than the US. Utterly ridiculous. Meanwhile if you look at the scores and see where the US is sitting, they are not dead last, but hardly anything to brag about. https://www.businessinsider.com.au/pisa-worldwide-ranking-of-math-science-reading-skills-2016-12?r=US&IR=T
