and Iran had biggest growth in USD millionaires worldwide,
Sorry but this is silly news.
How many Iranians are poor ? Does the wealth that those millionaires generate get distributed among the rest non-millionaires ?
In India during the COVID first wave last year when tens of thousands of migrant laborers, maybe more, migrated back to their hometowns and villages because of unemployment it seems the wealth of many Indian millionaires grew. They grew rich while those laborers suffered and others remained poor or trapped in middle class. Economic disparity.
