The most combustible problem with Southeast Asian economic growth is that it is concentrated in the hands of a very distinct minority (namely the Chinese - the Jews of Southeast Asia)
The communities coexist in relative harmony, but the wealth gap among them is grave. Despite making up 60% of the population, Malays own just 19% of the economy, trailing far behind the minority ethnic Chinese, who make up only a quarter of the population but hold 40% of the economy;
IIRC it's worse (wealth gap is bigger + tensions are even higher) in Indonesia and worst in Philippines.
