Thanks for your reply I am also looking to understand this report further I think I see what you're saying: The prices are already PPP (did you mean that instead of PPI?), thus the _additional_ adjustment of middle class as varying country per country (on a USD value basis) is then misleading/lying. E.g. Someone below the threshold of middle class in the USA may still be considered middle class in Germany. The issue I see specifically is here: >So the graph uses different definitions of middle class standard of living and conflates the results. They use a _consistent_ definition of 75% to 200% (a percent basis) of the median income in each country. What you interpret as different definitions stems from the fact that these countries have different median incomes. And that's the whole point of the category of "middle-class" isn't it? Consider the edge case of some fictional country where their currency is gold bars and diamonds. "In America you'd be rich!" you may tell a middle class member of that country. "That's great, but I'm middle of the road around here actually" Is what they would respond. The fact that a homeless person in the US, with their scant possesions, would maybe be wealthy in Yemen (ignoring the myriad other issues) has no bearing on their current condition in the US. If we compare these countries on a worldwide median household-income basis ($9,733 [1]), almost everyone in the developed world would be "middle-class" or higher. Would that mean there are no issues there? [2] [1] https://news.gallup.com/poll/166211/worldwide-median-household-income-000.aspx https://news.gallup.com/poll/166211/worldwide-median-househo...
