       | where everything is reduced to a one-liner. It's good that people
       | look at this sort of thing, but it's a losing battle.
       | 
       | It's basically impossible to compare anything across countries
       | without a huge number of asterisks, none of which will be read by
       | anyone. For example:
       | 
       | - Education. Countries have different standards for special
       | needs. The have different start times for first grade. They have
       | different curricula. Some languages are easier to learn. Some
       | have split school systems. Some have more private schools.
       | 
       | - Tax. Tax pays for different things in different countries.
       | Denmark has its benefit recipients pay tax on the income they get
       | from the state, boosting the headline amount of tax. All
       | countries have different tax bands, and the bands correspond to
       | varying standards of living.
       | 
       | - GDP. Some countries have a large dark sector. Some countries
       | are tax havens (no idea how that gets booked).
       | 
       | - Health. Some populations are more prone to certain illnesses.
       | Some populations are older or younger.
       | 
       | - Crime. What is defined as a crime varies.
       | 
       | I see it so often that we should look to country X because things
       | are going better there on some measure. But every time, I end up
       | in a rabbit hole trying to figure out whether people thought
       | about all the caveats.

         | do the bare minimum at school and expect a comfy life.
         | 
         | Same reason poor non-feminist countries have more women in STEM
         | than wealthy feminist countries.
