I agree, but a crisis is the ideal time to examine the root causes that led to the crisis and to re-examine the assumptions upon which the environment that led to the crisis were based on.
Fractional reserve central banking is a giant Ponzi scheme that leads to bank failures again and again. Any business that will fail if 20% of its customers use the product as intended (withdrawing funds from a demand account) is fundamentally unsound.
If we fail to learn from our mistakes we are destined to repeat them.
