New York Times just released an excellent series of articles that attempts to dial in on answering this question.
You can read those articles here.
From time to time, we come across articles that we believe may be of interest to the recovery provider community and are happy to share them.
So, in addition to our newsletter, we will share relevant content here (some new, some old).
Some of these articles state they are not to be reproduced or republished without prior permission. Since these articles come from sources freely available online, we felt it both legal and appropriate to provide them to you for review. All credit is to be given to the authors of those articles and the online publications from which them came.
