There are shrewed/sharp, motivated/ambitious individuals from any rich or poor country. Here I briefly look at the populous developing countries such as China and India. Some of these individuals receive a decent education in their (low-income) home country or as a foreign student in a developed country.
How about Singaporeans? When we meet a Singaporean abroad, we often see them as not-so-sharp, but with a rather resourceful government supporting them. So some of them are lucky kids, rich kids, if not all smart kids. These kids belong to a rich “extended family” — the Sgp nation.
Perception of Sgp nation is more positive. I will skip the list of adjectives.
