Why the secrecy?

There's a...'discussion' taking place on the pro-privatization Facebook page in the past couple days about taxes, markups, and the "bottle fee," and one thing that's come out of it is the lack of a straightforward exposition on just how much The State Store System jacks up the price of booze, and how. Which led me to this:

If the State Stores are a PUBLIC business, the markup, bottle fee, and all taxes should be posted in every store as a public SERVICE. 

How's that strike you? Sound reasonable?They keep telling us that the State Stores are an "asset" that belongs to us...how come we know so little about how our business is run? How about a little sunshine, Joe, PJ, et al?
