If they paired average metrics with gini coefficient, I'd be happy
Whilst it's common to interpret "average" as "mean", this isn't strictly accurate or reliable.
The Economist's article errs in failing to distinguish which measure of central tendency is actually meant by "average".
Others will find fault with the tiniest thing, even if 99% of everything is perfect.
And others can be incredibly content with very little. It gives absolutely no insight into how good life actually is anywhere.
And seems to vary with the economic situation just like everywhere else.
Plus quite a few North African countries ... well, they're just lying. Look at Egypt, even Tunisia ... these figures are just not possible, they're either misclassified or just lies.
Like are we just comparing simple goods: grocery, white wares, cars, fuel/electricity etc the price of these things there. Or are we also considering things such as: need to save money for Healthcare, University, credit card transaction fee, housing cost (mortgage), required amount of fuel for basic functioning of everyday life?
The latter is basically stuff that is either cheap or free in certain places while astronomically high in other (US, but I guess housing price is everywhere if city).
I feel like layman AND economist doesn't truly account (or even understand) how different some countries have it on those metrics; A person in Tokyo or most capital cities in Europe can get away with ZERO fuel + car cost, while for Americans that's a death sentence. Same for Healthcare. So comparing those prices doesn't even make sense to begin with, but leaving it out is a major boost to places where salaries are high (US) but the (hidden) cost are not measured.
Healthcare is absolutely not free anywhere. It maybe that the costs are indirect via government taxation and benefits are curtailed via rationing or simply unavailability of certain types of care.
Ofc it's not free. But the point is that in the way you calculate, it can present as free. My question is to what extent do they calculate
