If Singapore is homogeneous, the USA is too. Descendants of Chinese (majority), followed by Malay, and Indian make up most of the citizens. Couple that with the high number of expats from all over the world.
What? The country has four official languages. It is arguably close to the US level of diversity, especially when you consider the implications of how multiracial children are classified and the fact that 70 something percent of the country is put into a vague “Chinese” bucket.
Yes we should have a “War on Drugs”? What could possibly go wrong?
