Dick Fuld's Ignorance: argument for smaller Banks

When the former CEO of Lehman Brothers argues that he had no knowledge of the bank's use of an accounting gimmick to hide its deteriorating financial situation we may well give him the benefit of the doubt in the absence of a 'smoking gun' proving the opposite. But it also demonstrates that even managing a financial firm such as Lehman Brothers was beyond the capability of one manager. Lehman did not have all the other business units that the typical 'Universal' Bank has under its wings (Credit Card, Consumer loans, Corporate Banking to name a few) and it still was possible that the man in command - and given his length of tenure he had the ability to know the shop inside out - did not get involved in substantial transactions such as the regular Repo 105 transactions which involved billions in balance sheet exposure. The argument that breaking up banks into smaller units would harm the economy holds no water. Why should lending to industry, and in particular to middle-sized and smaller businesses be harmed if a bank can no longer play in - to pick just one example - the structured retail client product market in Germany?
