Just my recollection from having read the book - don't guarantee it is 100% as the book presented...
The opposite occurred with the Roman Legions. The Legions started out as a voluntary honor carried out by citizens -- no place for the family in that situation. Then being a Legionnaire became a career, and after awhile the rules changed so they could have families live with them. At that point, the "military industrial complex" was permanently cemented in place for that society.
The book "The Shoes of the Fisherman" by Morris West is a good fiction novel, sort of related to your comment.

Excerpt:
[ In an unforseeable literary coup, the book was published on 3 June 1963, the very day on which Pope John XXIII died.[2] The book reached No. 1 on The New York Times Best Seller List for adult fiction on 30 June 1963, and became the No. 1 best-selling novel in the United States for that year, according to Publishers Weekly. ]
I just googled about Quinn, and it seems he has played a role in some other famous movies too, including Zorba the Greek, Lawrence of Arabia and Lust for Life:
He also played the title role in Barabbas.
The scene between (actors) Jack Nicholson and Tom Cruise in which Tom tells Jack "I'm not your son, and you're under arrest, you $#%#%@^!" is a good one. I forget the name of the film though.
Another one is the scene in the movie Julius Caesar (maybe based on some classical novel about him, possibly by Shakespeare?), which occurs just before his death. Powerful performances by both the actor playing Caesar and other Roman officials of the time.
I believe the Catholic Church is the oldest corporation (they were the first non-human entity recognized by law as having similar rights and responsibilities as an individual).
I have no opinion on the truth or otherwise of this theory, but find it fascinating.
