This is one of those devil-in-the-details things about international comparisons, especially in the social media era 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.<p>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:<p>- 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.<p>- 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.<p>- GDP. Some countries have a large dark sector. Some countries are tax havens (no idea how that gets booked).<p>- Health. Some populations are more prone to certain illnesses. Some populations are older or younger.<p>- Crime. What is defined as a crime varies.<p>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.
