My main turnoff in Singapore after living there is the explicit racism that is a part of its social hierarchy. A fresh college grad who is Singaporean will earn more than a much more experienced veteran doing the same work, if that veteran is, for example, from the Philippines. There is a lot of what other countries would consider slave labor disguised as "opportunity" for those from more disadvantageous surrounding economies. This lack of equality runs deep through all the different social constructs of its culture.
