Actually his post reminded me of what led to Lehman Bros collapse in 2008 and the entire economy cratering. https://en.wikipedia.org/wiki/Lehman_Brothers Lehman's was big into CDS' selling them for people who owned MBS' as a hedge should the borrowers not repay their loans. https://www.investopedia.com/terms/c/creditdefaultswap.asp Oops times two. The MBS' collapse and Lehman's defaulted on their CDS agreements and no one wanted to save them. And somehow it's all Fannie Mae's fault.
