Building engineers ensure everything is to code. Architects fret about whether it looks and feels right.
Some architects are good at making livable spaces, but an architecture degree doesn't guarantee that, and a lack of one doesn't preclude it.

Prima donna "starchitects" worry less, but that's because they've hired other architects to handle it.
