A special report on the future of the state: Go East, young bureaucrat | The Economist: "Western civil services often have pretty good people at the top, but in Singapore meritocracy reigns all the way down the system. Teachers, for instance, need to have finished in the top third of their class (as they do in Finland and South Korea, which also shine in the education rankings). Headmasters are often appointed in their 30s and rewarded with merit pay if they do well but moved on quickly if their schools underperform. Tests are endemic."

What would U.S. teachers and their unions say about this?
