That's exactly right, despite the misnomer "living will", NONE of these alleged solutions have been tested in a real inevitable financial crisis.
In 1929 there was the Great Depression, roughly 80 years in 2008 there was the Great Recession/Financial Crisis. Each was characterized by a loss of investor confidence.
The government thinks it has come up with a solution with the 'living will' concept and plan required by all TBTF financial intermediaries.
If the next inevitable financial crisis occurs 80 years from 2008, I doubt many of us will see if the 'living will' solution works.
