It’s almost unheard of for a child to show up hungry or homeless. I don't see how this author can fail to make any mention of the vastly different demographics in Finland as compared to the US. Certainly the US system has problems, but acting like the solutions are so easy doesn't help anyone. Finland has one of the most even wealth distributions in the world.

I'm 100% convinced it's something else, specifically that (in a lot of cases) the system itself causes the behaviors by motivating/incentivizing it.
