In SG, they can also plan for decades ahead because of a more stable political climate where people actually respect their government for most and ACCEPT that there is some humans that are considered "superior" and take the lead, it's a huge difference with the west where people favorite sport is to non-stop shit on their government or denigrate without offering solutions, in the west, we seem to not be able to accept that there is even a class system where people have more power/rights than others (while there is, it's inevitable).
Singapore is the third least corrupt country in the world[1]. Another country that has managed to pull off successful public housing, Finland, is the second least corrupt in the world.
The United States meanwhile is in 29th place (and that's being generous, imho) and at its worst ever in the corruption index[2]. It's been falling for a decade. Perhaps that's the real explanation: we can't have nice things because the resources needed to build and operate them are actively siphoned off through embezzlement, bribes, kickbacks, and fraud. Rigid class systems don't do anything to prevent fraud, either, in fact they entrench it deeply.
