Yes they are.
I would think most of those should be checked anyway as a lot of them are, in my opinion of course, way too high for what they give.
Some are basically free and give higher bonuses than others that are WAY expensive. And this is in normal buildings.
As for Wonders it is even worse. Water Pipes and Energy Lines Departments National Wonders giving buildings free in every city for a cost of 16
(Deity)? I am better off building Water Pipes and Energy Lines separately in every city instead, as they cost in them selves too.
