We are spending two and a half times more on public education than we were in 1970. Academic results are flat. Meanwhile teens are killing themselves 3x as much as they were in the 1950s. How can government schools be a good investment when they are increasingly damaging to children while costing more?
See AEI animated chart below on the increase in spending along with pointers towards data showing flat academic outcomes.
For solid data backing up the graphic at the top, showing an increase of 20% in teen suicides during the school year, as opposed to summer and holidays, see:
Hansen, B., & Lang, M. (2011). Back to school blues: Seasonality of youth suicide and the academic calendar Economics of Education Review.
What part of "Quit spending more money to kill more kids?" is hard to understand?
