Levelling wages to graduates

Some saying that university graduates are getting more and more difficult to grasp a well-paid job, unlike the old days in Hong Kong. However, such a situation also happens in the States. There is a report in Monday's New York Times about the narrowing differences between bachelor's degree holders and high school graduates. The issue relates to economics: the demand for university certificate has been saturated; and there is not much distinction between college and high school graduates.

Indeed, I do not concern too much on the wages, especially for those competent graduates (even though I know sometimes the starting points are not really attractive). They would finally get what they want at the end (and it might not be money). Nevertheless, there should be something valuable when you have a chance to learn in a tertiary education institutions...and it is surly not necessarily relates to earnings.
