VIDEOPerhaps the most amusing part of James O'Keefe's recent OMG video about BlackRock was when recruiter Serge Varlay explained the economic theory of the "Inverse Cramer" in which one can make money by doing the opposite of what CNBC's Jim Cramer recommends. Therefore I thought it would be interesting to see what Cramer's thoughts about BlackRock and its CEO Larry Fink were over the years. As you can see, Cramer has given a big thumbs up to both BlackRock and Larry Fink. What could this mean?
