I have been having a lot of conversations about education in America. This is quite a complex issue. One thing that is really bad is the quality of education if really poor. I recall reading in Forbes magazine that 20% of Fortune 500 companies have to teach their employees basic ABCs and 123s. I know this is harsh thing to say, but many in USA are not even worth the minimum wage, at least from a global perspective. In one train of thought, maybe there should be a mimimum requirement of GED or high school diploma to receive the mimimum wage. Companies have to import educated people from other countries as there's such a dearth of people edcuated with science degrees for example. USA is becoming uncompetitive in the world due to the lack of educated citizens, especially in areas of science and math.
For the topic of high school diplomas: what does that really mean? Can the high school realistically quantify the student's knowledge? Are teachers certified in the subjects they teach?
There is some momentum to have common state exams in California require for getting a diploma, but there we don't have a mechanism to certify the teachers. Actually, the problem is trying to attract the teachers, as there's little incentive to do so with a shoe string budget that will not even pay for the cost of living in some areas where they teach, such as Cupertino, California for example. The emphasis and priority in education just isn't in place right now in USA. We pay more on hamburgers than education, according to the book Fast Food Nation.
This is a big contrast to places like Korea, where at one point they realized they would always be exploited by others if their citizens are not educated. Now they are really successful and many are brilliant students with amazing abilties to study and memorize.
