Every decade or so, with regularity, the world seems to go through a significant economic or financial crisis triggered by some or other "unexpected" shock:
* The current crisis, starting now, in 2020;
* The global financial crisis from 2008 to the early 2010's;
* The dotcom, telecom, and tech bust of the early 2000's;
* The Asian debt crisis of the late 1990's;
* The Latin America debt crisis of the 1980's;
* The oil shock and stagflation crisis of the 1970's;
In each of these crises, a significant swath -- or all -- of the world's financial infrastructure has seized up, requiring government intervention to prevent collapse.
A natural question to ask is whether the financial infrastructure we have today has been well-engineered to be robust to these remarkably regular shocks.
Judging by the regular seize-ups, it doesn't seem to be.
