 FEM is easy to setup.  It is not complicated. 

Nonsense. If FEA results are to be trusted, the person doing the modeling needs to understand the physics of the problem. Nowhere is this more true than with seismic work, but it's pretty much true for any engineering analysis. You can't separate the model from the physics that the model is supposed to mimic. Some kid who doesn't understand the notion of a load path or modal response combination is likely to ignore or misinterpret important design features because he doesn't understand their significance.

It's like that with CAD, too. Too many think that an engineering design is just the pictures--it isn't. It's an organized communication of information required to produce an artifact. If it's not organized and unambiguous, things get screwed up and left out. You can't just put a CAD monkey in front of a monitor and expect engineering design.

CAD and FEA are tools, not solutions. The effectiveness of a tool depends on the abilities of the individual using it.
