Australia right now is in the grips of horrifically bad government policy in this regard (the CSIRO pretty much fired 2000 post-docs, so the market is now completely glutted with people with more experience then anyone graduating recently).
And when you get right down to it, this is all a huge stupid waste. We sink the cost of educating these people, then proceed to toss them into menial jobs which don't use those skills at all, don't provide opportunities to maintain them or anything like that?
