Saving for retirement is important, and it can be hard to find money to set aside. But according to the Employee Benefits Research Institute, even people making $100,000 or more don't always set enough money aside to retire comfortably.

In the following video, Dan Caplinger, The Motley Fool's director of investment planning, looks at the EBRI study, noting that 12% of those making six figures have less than $25,000 set aside for retirement. Dan points out that there are some short-term situations where that can make sense, such as paying down loans and other debt or saving for more immediate needs. But in the long run, high-income earners have no excuse for not saving for retirement early, and they'll have even more trouble getting accustomed to a greatly reduced standard of living if they don't.
