There are a lot of details, and it's definitely the case that countries like India, China, Mexico, Bangladesh, etc. have benefited tremendously from economic development. But it's also the case that the US (and most of the West) is experiencing levels of income and wealth inequality not seen since the beginning of the 20th century. The profits from these economic miracles is indeed going largely to a very small number of people, even in the aforementioned countries (China's poverty statistics are frightening, for example, even by their laughably low standards).
