The correct answer is - East Asians.
Ecuador and Peru are South American countries that have very diverse populations, but are also known for having populations that are mostly of indigenous origin. There's also mestizos, white people, black people, and East Asians. The East Asians are the smallest of the groups, mostly represented by the Japanese and Chinese.
This group, over time, has managed to become from ordinary workers to people that have their own businesses, own large companies, and be one of the most prominent politicians in these countries. This has led to a situation where the smallest population group in these countries is actually controlling the biggest portion of the money, as well as having the biggest power.
