In our modern society, no matter whether you are in the U.S or in China, a large number of well-educated personnel is needed to meet the demands of different kinds of positions. It's hard to believe that anyone can find a good job without higher education. Based on statistics, many Noble prize winners are Americans. If we compare the American higher educational system and the Chinese higher educational system, I think these two main reasons stand out as follows. Even though both the U.S and China have college systems, which are nearly identical in appearance, they are quite different in practice.
China has a very competitive college entrance examination and very strict grade requirements.
Under this system, Chinese students study very hard during high school. They don't pay much attention to the outside world except their textbooks. So, many students with high grades, but low capability are created. They lack the ability to communicate with other people and their mind is closed. Unlike China, the U. S does not have any college entrance examination.
