As a bank worker in a no engineering tech role, I think the myopia you describe is IMO a significant factor. From a retail banking perspective, many banks are starting to modernize their practices and play catch up for mobile. But most banks are stuck in rigid methodology, culture and solutions established in what I call the first generation of online banking. Projects are treated as continuations o this foundation and continue with antiquated development methodologies and back end technology. Since acceptable products get shipped, there's no business incentive to modernize.
