Banks this and that ...
I'm a retired electronics engineer that focused on wireless communication technology (because I'm curious about things invisible), but I took a couple elective college courses in economics and banking while in college and developed the belief that there are more than enough regulations and regulators and computers that know everything, and have all the data they need, such that if current regulations are followed then that would guarantee a robust banking system that could not fail.
With that in mind, when a bank fails I would blame the regulators and not the bank itself. So I'm thinking that a good number of regulators (government employees) are spending too much time going to parties. I know for a fact that all bank activities during each working day are transmitted to its assigned regional federal bank overnight. So there is no excuse for regulators not having sufficient data to complete any of their assignments.
While I was still working as an electronics engineer a technician and I had to go to Washington DC to talk to some standards group about wireless communications standards and regulations. During the evening we went to some of the local bars. That's were we found a good number of our public officials getting drunk as a skunk. That state of mind probably interferes with their regulating, and that might be where they cook up some of their excuses.
