While I'm on the subject, what is with driver's licensing? Even if I accept that licenses are really are a good idea why do I have to renew it every two to five years (California)? I was awarded a High School Diploma in 1970 and it still as good as the day I got it.

Since High School I've manage to earn BSc degrees in Engineering and Telecommunications. I've never had to renew those either.
