I suggest you read on. In my experience there are many ways multi-million and multi-National corporations have of mitigating their risks without having to rely on the FDIC coverage. Rule number one: diversify (and that includes your banking relationship).
The fact that this apparently fundamental rule is forgotten shows how much we as a society have come to expect Uncle Sam to bail us out.
I would say it's more a function of how rarely banks fail in the U.S. anymore.
