When I was an elder many moons ago, the WT came out with it's free literature change to aviod taxes, before that it was encouraged that all congregations pay for all litterature in stock instead of the WT doing so.
This no doubt was done to make it more profitable for the WT and in antisipation of a loss in the tax case with Swagert and the state of California of which the WT was envovled.
This in my estimation was a big blunder as many congregations were not paying enough in contributions to pay for the literature they now recieved free. The case in my congregation I'm sure was typical of congs everywhere as the poorer friends used it as an opportunity to stock up and get some of the more expensive books that would complete thier libraries at home and in the process failed to give the needed contributions for literature.
In my congregation the CO gave instructions to the lit servant not to get these more exspencive items for those that looked like they wouldn't contribute enough, this put an unecasarry burden on the lit servant to be the bad guy, and he came to me and I told him order anything the friends want and not to deny anybody it is not your responciblity to decide,, let the Society decide if they want to. As I felt this to be wrong and put the MS in the place of judge as to who gets literature and who don't depending on ability to contribute.
Well it seems years latter now this has been a real source of finacial loss for the WT(yeah!). Cheaper books (paperback), bethel downsizing, and now COs being done away with.
Yes the friends (JWs) are voting with thier lack meeting attendance and contributions. The decline is steady!!
