I've noticed this trend for a while now. I agree with the article when it says most older workers are happy to mentor the younger workers, but the problem is that the businesses just aren't hiring both very often. I don't blame businesses for doing what is best for the company and I don't blame the boomers for continuing to work. It just doesn't really help the future generation if they can't gain experience now.
Generation X is a whiny, crying generation who expects everything given to them. I think learning from the boomers as an apprentice might be the kick in the ass they need to help our country move forward. If not, we are in big trouble when they are actually getting these jobs without proper training.
