Are there really differences between the generations?

Here is a quote from the weekly Herman Trend Alert that I find very interesting considering everything that is being written about the differences in generations.

"As futurists, we have long touted the value of older workers, with their experience, stability, and wisdom. We have also said numerous times that employers must be more flexible with their older workers. Allowing greater flexibility in scheduling and work location will give employers a competitive edge in retaining these senior workers. Wise employers will conduct stay interviews to prevent untimely losses of these valuable human assets."

This sound like a quote right out on an article or research paper on the Y Generation.
