I work for a bank in the US, and not one of the names you hear associated with scandals all the time. The level of redundancy and HA built into our everything is why our jobs are so boring and slow. We also use a core banking platform that lots of other banks use and it's properly engineered for the kind of enterprise performance we'd all expect. There are certainly problems in banking, but the FDIC protections are also there for consumers. Let's start with a reasonable premise, not a fear-mongering one.
