As is often the case, the experience of individual countries is more revealing than the averages. China started with less education than Tunisia, Mexico, Kenya, or Iran in 1960, and had made less progress than them by 2010.
通常情况下，各个国家的经验比平均值更能说明问题。中国1960年开始时教育程度还不如突尼斯、墨西哥、肯尼亚或伊朗，到2010年所取得的进步也不如上述国家。但在经济增长方面，中国却完爆这些国家。同样的情况也出现在泰国、印度尼西亚与菲律宾、喀麦隆、加纳或巴拿马的比拼之中。同样，增长较快的一方除教育外还做了其他工作。
