Buildings scale off of tech and empire size, units off of tech. I did this because many units also have building requirements for purchases in the later-game.

I understand now why it was implemented this way, and at the same time that was probly awhile ago now. If there is a goal in mind to reduce wide purchasing power, the malus should be applied somewhat uniformly across all available purchases, otherwise it'll wind up creating a skew towards one thing or the other. I've always considered that units require buildings to be purchased just a game enhancing flavor piece (although it occasionally stymies me, I like it), it never occurred to me as part of the gold balancing act.
