A well functioning financial intermediary system is important to a modern economy, but we've had a wee bit of proof over the last couple of years that our financial intermediary system is neither healthy nor much of a financial intermediary system.

Not a bad setup, for the banksters, but not really something we should encourage or think is important to preserve.
