I think it's a bit judgmental to tar all pioneers with the same brush as far as their motives for pioneering are concerned. we don't like the JWs making sweeping generalisations about our apostate motives do we? Coming from a family of regular pioneers (I was the only one who didn't) I rubbed shoulders with a lot of them in my old congregation. Yeah some are egitistical and may be doing it for praise but I would suggest far more are guilted into it. you know the situation - the talk says what prevents you from doing MORE? Why aren't you pioneering?! This is life saving work, what else can be more important?! I'm thankful that my mum, a regular pioneer for many years actually discouraged me from pioneering and suggested I get a"proper job" first so that I would be able to support a family.
there are lots of criticisms one can throw at pioneering and the pioneers themselves but to make sweeping generalisations is not the way to go.
