Back in 1974, the Watchtower Society was still selling literature from the literature counter. They were encouraging JW's to increase their time in the ministry work and even pioneer if at all possible.
The more preaching that was done, the more literature at the literature counter was sold, which would bring a financial gain for the Watchtower.
The Watchtower has always had some sort of trick up their sleeve to make more money.
That Kingdom Ministry letter suggests all kinds of ways for families to change their circumstances to get out into the ministry work.
They are still doing this today in one way or another.
Now the Watchtower is making mega bucks on real estate and making hardships on JW's to get to a KH.
But the Watchtower doesn't care about JW's! They care about the $$$ MONEY.
Atlantis!
