How do I fix up my economy when my building maintenance is too high then?

Also, how do you know how a particular unit's maintenance is? I see no information on this anywhere.

Huh? Where's the gold piece? I don't have this, neither in the civilopedia or in the production screen, only for buildings. Am I looking at the wrong place?
