This is a good article and everyone should read it -- it's short - but long on ideas and values to be remembered. The values are that it really doesn't take that much per year or that long - to accumulate some meaningful funds.
The strategy is that investing is not about getting rich quick - but rather - time is the wealth creator... the sooner someone gets started the better. The author uses 12 years to show money growth. If money doubles every 10 years - then the 167K is going to be 330K and the author is assuming that you quit saving after just 12 years. Of course he's not writing about that - but I'm taking his example just a bit further.
Now imagine - that if a person really said to themselves... RETIREMENT should be fun - and fun costs money. And then saved accordingly. To me - I think if someone is making 100K a year... they should easily be putting away 1K PER MONTH... which would double all the authors results.
