On a rather long, often delayed trip to the West Coast, I had the opportunity to read Crash of the Titans: Greed, Hubris, the Fall of Merrill Lynch, and the Near-Collapse of Bank of America by Greg Farrell. While it is a fascinating tale of the clash of two very different organizations, one about to fail and another on life support, it was of particular interest to me as a former BofA employee. The descriptions of the culture of the bank and in Charlotte was spot on.
I became an employee through the merger of a bank in Baltimore to NationsBank in 1993 , the predecessor of BofA. I remember the teams pouring in from Charlotte to help us "learn" the bank's way of doing things. Even then, it was clear that we were the acquired and they were in charge. It was described as a meritocracy and it was; if you hailed from Charlotte. Based on this story, that appears to still be the case today.
With even a slight understanding of the history of Merrill Lynch, you can only imagine the conflict. This is a great read and gives a good behind the scenes look at the near collapse of the financial system.
