Why do you think young adults are concerned about retirement?

I came across the article Young Adults Concerned About Retirement recently.  Statistics from the Ipsos study include nearly half of the 25-34 year olds polled fearing they will not be able to maintain their standard of living in retirement.  While young people typically have the least amount saved across the generations, they retain one asset older Americans can never get back: time.  As such, I hope our nation's young folks use this fear to take action and begin saving now.  Of course, if they had, they might be less likely to be fearful.   Hmm, does that mean the other half are saving aggressively or are living in denial?

What do you see?
