Is dividing the finance industry into depository institutions and investment banks sufficient to avoid economy wrecking catastrophes and atrocious misalignment of incentives? I suppose half of a 16 oz porterhouse would be easier to swallow than the whole thing. It might even be possible to ingest the fillet portion without requiring the Heimlich maneuver. Downing the rest, bone and all might provide a significantly greater challenge. There's a fundamental problem with the manner in which large investment banks deal with their customers, their creditors, their investors, the rating agencies, other financial institutions and the government, and none of those are solved simply be separating the depository portion of the business from the riskier portion.
