From life experience, guys with 10 years DBA experience do feel bad when they see jr. dbas with OCP. Recent Graduate unemployment shouldn't stop high school kids from thinking about college. No knowledge is useless paper, certificate or whatever
Biggest advantage with OCP (as long as you didn't cheat), is the exposure to all aspects of the product. You may not fully understand a concept, but you are aware of its existence and how it might be used to provide a solution.
I recently ran into a data warehouse system designed by an experience DBA (3 years+) ... the DBA had no idea of bitmap indexes and how they can be used on columns in a where clause with low-cardinality.
There is such a thing as experience and then there is real experience. I have ran into guys with one year who would run circles around guys with 5 years that never did much more then change back up tapes.
