They are developing countries only because there wages are small and only 1% of the country have the luxury most EUROPE and USA had ten years ago. It is not about technology and all this. Yes in the past 2000 years ago Asia was more developed then EU and USA did not exist in a map, but nor did the capitalist world which is today.
When you go to some places in China, India and Brazil and see people dieing in hunger you understand what I mean. It is not about the building and skyrapers and all this stuff it is about how most of the people live in a country. In China and India workers have no right and if you have a factory you can do what ever you want. Kind like USA in the great depression. I am surprised you dont know about all this saying you study history so much.
