Many of those DO's and C.O's and their wives spent most of their lives in working for the Org. When they reached retirement, the Org. left them entirely to the "tender mercies" of the Congregation they ended up in.
I don't know if that has improved over the last decade or so ?
I expect a good number that I knew in my decades in have died, and a number more are not far off. A huge number of sad , wasted lives we are mentioning on this Thread.
