It's a failure of education. This is one reason why everyone should have a basic understanding of code: not so they can all become programmers, but so they can get a mental handle on these systems and the people who do program them.
It's the auto-mechanic problem; if you don't understand the thing yourself, you have no way to know whether or not you're being taken advantage of. So you tend to just split the difference and maintain a constant, moderate skepticism.

One always seem to think solutions were quick and easy, but that's because he never got to the stage where he could write reliable maintainable code. We were constantly fighting fires and he seemed to think that was normal.
I am not convinced that giving people enough knowledge to be dangerous is a good thing.
Because like writing and basic arithmetic, it's relevant to some degree in the majority of other fields. Code is used in medicine, quantity surveying, manufacturing, film, oil drilling. It's a field that cross-cuts fields, and decision-makers who don't have a basic understanding of it are going to make worse decisions no matter what their organization's primary focus is.
