1. JW's are not particularly cleaner than other people. Many are just the opposite. It is simply a convenience for JW's to become cleaners, windows, office etc. because it takes little mental effort and believe it or not they can do it without paying taxes because it is often a cash transaction. Others justify that they don't make enough to pay taxes and don't report it. The sad thing is there is no Soc Security points and thus no retirement. They will regret it. It makes it easier to schedule conventions and such when you are your own boss.
2. Yes, guilt runs deep. People leave for various reasons. Most to escape the pressure not the doctrines. Those that leave for doctrine seldom return. Everyone else is likely to have at least one relapse. That was me the first time I left. This time? No guilt, just education.
