It seems like a simple task to determine the wealth of countries but the experience of living in a country is influenced by many other factors. Being wealthier matters a lot less if everything you have to buy also costs more, while a country where you have the same spending power but work fewer hours would likely ive you a better quality of life than you might expect otherwise. And that’s before we move onto the question of who gets to enjoy the wealth created.
