you disagree that it's significantly easier to make changes in a society that's more homogeneous? NYC could jettison itself off from the rest of the country and be a model state. but nationally, poor people and religious fundamentalists and radical liberals all get a vote too.
Singapore is anything but "homogenous". It's one of the most ethnically diverse countries on the face of the planet. Additionally, as the article pointed out, the system is based on Germany's (population 82 million) education system of getting young people ready for the working world. This is one reason Germany's manufacturing sector dominates much larger rivals.
Here's another Op/Ed from Thomas Friedman regarding Singapore from last fall:

Additionally, Singapore is governed well because it pay smart people well. Many government officials in Singapore make over $1 million per annum, with the bonuses tied to GDP growth and other performance bonuses.
At some point the US will have to face these issues, and change. It will either be forced upon it, or the US can take it upon itself now to make serious steps towards change.
