This sounds very similar to the Church’s past practice of people buying indulgences. I was raised Catholic, by the way.
But, I’m not surprised.. I always felt (even during the time I was active in the JWs) that their constant criticism/ridicule of the Catholic Church was just plain old envy.. I remember it was a total turnoff to a visiting lady when this was done from the platform.. She felt that ‘knocking other religions’ was in poor taste.
It’s entirely possible the future JW religion might resemble a little bit of what you said combined with televangelism.
