Financial innovation can be highly dangerous, though almost no one will tell you this. New financial products are typically created for sunny days and are almost never stress-tested for stormy weather. Securitization is an area that almost perfectly fits this description; markets for securitized assets such as subprime mortgages completely collapsed in 2008 and have not fully recovered. Ironically, the government is eager to restore the securitization markets back to their pre-collapse stature.

The government can indefinitely control both short-term and long-term interest rates.

It is crucial to have a strategy in place before problems hit, precisely because no one can accurately predict the future direction of the stock market or economy.
