Scaling the level of cult control within the JW organization on a scale of 1-10, I would say bethel life is probably a 10.
I ended up in a downtown big city congregation, and it had a high influx of uber zealous young people from other parts of the country. And, as controlling as the WT publications are, some elders managed to find ways to add more rules. A very controlling P.O. made sure we had regular local needs' talks with stuff like: "some of the brothers in this congregation are very unbalanced with their amount of recreation. Balanced recreation only requires OCCASIONAL recreation. In this cong., some are socializing SEVERAL TIMES / WEEK! That doesn't leave a person refreshed, then they are tired for FS" We were also repeatedly councelled against working in service with our friends, of arriving at the group pre-arranged.
There was also a huge amount of social pressure to "pioneer", stay "pioneering" or go to "bethel". I got the feeling that normal things like buying a house, going to college or having a normal job put someone on the fringes. But after visiting a few other congregation, I saw that some were so much more chilled. Everyone, including elders and their children, going to college, having careers, buying bigger homes, without any feeling that there was any pressure to do otherwise.
From my perspective, the contrast made those more liberal congregations seem like any other protestant religion.
But then the odd thing happened. After word got out that I had stopped attending meetings/FS, the friends I had that were in more chilled congregations were just as harsh on me for "leaving Jehovah". So I saw it's a cult, no matter what degree of cultishness.
