High school needs to be "graded" anyway. FAR too many people in this country go to college now.... people that have no business attending go for a "business" degree because the average-run-of-the-mill secretary has one now. There needs to be college-track high school curricula, as well as "I'm going to go work" curricula. There's no point in someone who is going to be a welder taking European History--but it might benefit him to take Personal Finance or Microeconomics.
The real reason this hasn't happened (creating "college-track" schools and non-college track schools) in the vast majority of situations is that 1) school districts like to use intelligent (generally well-behaving), good students as behavior modification for rowdy students, 2) it would be difficult to staff the "lesser" schools, and 3) we stick to the "you can be anything you want to be, as long as you try" anthem FAR too much.

Incompetence when addressed about this type of thought.
In all seriousness, we need to meet the needs of our students. Most high school graduates are ill-equipped for their next few years--whether they go to a university (because, as in the US News and World Report states, they slacked off their senior year) or go out in the real world (where the British Lit and Algebra II they took their senior year is rather pointless for their new job as a brick mason). There are always exceptions to the rule (hell, I was dual-enrolled in a local university starting in ninth grade)..... but for the bulk of the population, I don't think we're meeting their needs--mostly because we refuse to accept that not everyone is "equal" (note: we're ALL equal in the eyes of the law--as the Constitution says--but, THANKFULLY, we're not all "equal" otherwise).
