I used to teach an under grad engineering class, does that count?

I hope I do contribute some knowledge to the young folks I work with, but most of them are very bright and won't need much help from anyone to do very well. What I am "concerned" about is the fact that only something like 30 percent of americans have a four year college degree, that needs to improved if the US intends to maintain it's current standard of living in a "knowledge based economy." Other societies that put more value on education are likely to do better in this environment.
