Does Generational Difference Matter?

I like this article on generational differences in the work place. Yes, this topic has been done to death, but it summarises many of my thoughts on the topic (which in a nutshell is that generational differences don't really exist but people at different life-stages naturally have different outlooks)

To summarise some of these points:
Similarities

• Everyone wants respect
• Trust matters
• People want leaders who are credible
• Organisational politics is a problem - no matter how old / young you are
• No one really likes change
• Loyalty depends on the context, not on the generation
• It's as easy to retain a young person as it is to retain an older one - if you do the right things(don't necessarily agree with this one - but perhaps that my personal experience)
• Almost everyone wants a coach (again, not 100% sure about this one. I don't disagree though)
  

Differences

• Longevity - young people are more mobile (which, to me, contradicts the second to last point above)
  
• How knowledge gets transferred (I've come across this a lot)
  
• Expectations of work
