I read the article. And see zero evidence given that letting kids survive is a bad thing if you trade in nothing important.
Then again, this seems US centric.
But this comment just seems cruel, making people think it is their fault if they have bad feelings.
The whole discussion is US centric.
In France kids are still free to roam around, or stay alone at home at 10yo (sometimes younger).
In Japan kids start commuting to school, sometimes taking the train alone, at 6.
