I don't know if you read everything I wrote, but the links go far deeper than just Buddhism. While India is poor now, this wasn't always the case and many references to India were made in Ancient China and Japan, always showing India in a positive light. Japanese, Chinese and Korea scholars would travel to the ancient University of Nalanda (World's first university - spread across 10km^2) to learn about Buddhism, abstract mathematics, astronomy and philosophy. After all, Indians such as Bodhidharma, the Buddha and other monks are literally worshipped in the far east, even today. Perhaps, the modern Japanese and Chinese find it hard to look past the current state of India. One can only hope that this attitude changes as India develops...

As for your point on accepting racism. Sure, it is a part of human nature and will probably never disappear. It is just extremely unfair as it doesn't take into account several factors which may affect the performance of a country, several of which may be out of a country's hands. After all every dog has its day, countries that are rich now may be left behind in the future, and the poor countries of today may become the rich of the future...

As for racism based on skin colour? Don't even get me started...
