It may be a conspiracy but it’s not a theory and it’s actually legal because the con men running the show say it is.
Bottom line: FDIC is bankrupt as would be most of our banking system if they marked all their assets to true market value today.
Repeat: the organization which insures bank deposits from bank failure losses does not have the money to pay off its insurance claims if all of the losses were revealed today. As long as people continue to ignore this truth then all can appear to be OK (just like they ignored warning signs about Madoff for a long time and continued to believe that they had real money in their Madoff accounts). But, if people lose confidence in the ability of FDIC to ensure them, they could pull their money out of banks (AKA a run on the banks) causing more banks to fail suddenly thus suddenly leaving the FDIC with a bunch of unpayable claims to pay. As in all Ponzi schemes, the key word is suddenly.
