Pillar's President is a convert to passive investing after working for 15+ years in various roles within institutions doing active management. Many investors who have heard about passive investing or have dismissed its merits with a wave of the hand (without doing due-diligence) would benefit greatly from the rigor and discipline (and results) associated with passive investing.
IFA has created an excellent review of the relative merits of active vs passive management. It is an extremely thorough analysis. But be warned - do not expect to remain an active investor once you have read the analysis!
