> If the complexity of what you are solving is in the business logic or, generally low, you are absolutely right.

The problem is rather that programmers who work on business logic often hate programmers who are actually capable of seeing (often mathematical) patterns in the business logic that could be abstracted away; in other words: many business logic programmers hate abstract mathematical stuff.

So, in my opinion/experience this is a very self-inflected problem that arises from the whole culture around business logic and business logic programming.
