What are we seeing here? Does this only illustrate the spread of the respective allocation? So its doesn’t show how much money a Government spends per capita or how efficient it’s being run for example. Or how?

add: for example if country Sweden taxes 50% and spends 10% on education, and country US taxes 30% and spends 10 % on education. Then how does it show?

I bet most of US “Public services” spending goes to militarized police.
