I agree. The most important factor was how the Singapore Government cleaned up its act not only by raising allowances, the carrot, but also the stick. Countries can plough in money into infrastructure etc but what happens when the money gets siphoned away or simply runs out? Another would be the level of coordination within the government, a natural advantage due to its size. Still, this is something all countries can work on. Last, invest in education. High quality education begets a high quality workforce.
