In the newest issue of the Jewish action, there is a discussion (under the title, the Generation After) of the children of Baalei Teshuvah and how many don't stay religious.  The purpose of the two articles at first glance is to present why this happens.  Unfortunately, in my opinion, neither author truly gauges the problem and instead relies upon generalizations to make their claims.  Yes, we can blame it on materialism or on the lack of tradition within the family or even that lack of modern Orthodox "kiruv" professionals.  "Dropouts" occur for more reasons than one can fathom.  In order to determine the reason for this phenomenon, one would have to look at each individual case of why someone became religious in the first place.  Every baal teshuvah has a different story leading to the path of becoming more interested in living a Jewish life. 
 
In terms of how to combat the "problem," there is also not one answer.  I think the intellectual side of becoming Orthodox needs to be revamped to include the latest academic rhetoric.  No longer can we rely on the so-called proofs for G-d's existence and Revelation at Sinai.  It is not enough to have a basic background in philosophy.  We need to expand our vision to include the latest in thinking. 
 
We also need to support sensitive and well trained people who are knowledgable in the trials and tribulations faced by the baal teshuvah.  Perhaps, we need to encourage those who have already gone down the path to be the one's to help those looking to travel along similar roads. Of course, knowing many baalei teshuvah, they want to be part of the mainstream so much that they would never want to share experiences with others.  However, if one so chooses, then the guide must remember that it is not the same path that he/she took.  The key is recognizing that each individual is different and different things work for each.
