First of all, the quality of our "worldly" friendships is so much better than what we had in JW land, so, we wouldn't return for that.
My JW in-laws are judgemental, unkind hypocrites, and would be regardless of what form of religion they were a part of. So, we wouldn't return for them.
There's actually one area where I could see a financial benefit, however I can't imagine returning to Watctowerism just for a buck.
