The financial system needs to be more than what FT currently wants it to be
Unfortunately, as a consequence of the world not having debated the purpose of the financial system for now some decades; and the financial regulators having just concentrated on lowering the risks of individual bank failures, your prescription seems about right. To me though the role of a financial system should be to move the financial resources to the most productive areas for the society at large, and that is an entirely different proposition.
