Morph you do realise that there’s no such thing as a congregation with one person? You are not even making sense, which always a good indication that it’s time to rethink your position. If you can’t explain your view without resorting to nonsense it should tell you something.
I just realised that one unrealistic part of the scenario I provided above is necessarily the reduction in pioneers. In reality I think pioneer numbers have increased in recent years. But once again this just shows you need to be careful with definitions and numbers. When I was young being a pioneer really meant something and often included people who significantly altered their work/family/life situations in order to spend considerable amounts of time going door to door. Nowadays there may be more pioneers but they are largely auxiliary pioneers who spend 50 hours or less per month, and they are mostly older people who don’t need to alter their life situations in any significant way in order to claim the badge of pioneer. They don’t even need to do all that much ministry these days because of carts. A whole generation of baby boomer JW have claimed the badge of “pioneer” as a sort of retirement pastime. Which is significantly different from what it used to be. So comparing raw numbers in this case, once again, is not comparing like with like.
