Real change in public expenditures on higher education, 2008 to 2023, selected countries that actually publish the damn data. UK is worst here, but note this does not include RAB (projected future loan forgiveness, basically). If RAB is included...UK would still be last.

I'd love to fund studies of interventions that reduce real-time pollution exposure, in the US, on outcomes related to violence and criminal behavior.
(There is strong evidence that such exposure increases violence in real time; the next question is how much interventions can mitigate this effect.)
