Company town. That's exactly what I thought when someone upthread said "Why don't they 'just' quit?"
I was raised in an isolated company town. I was a kid, so it didn't affect me personally, but if you quit or were fired, you had nothing left.
There was no other work, if they didn't want you, you had to leave: your home (rented from the company), your friends, everything you knew. Sure, you could take your possessions, your family, it wasn't slavery, but you were uprooting your family as well.
And the company
liked to hire family men,
because it was harder to move. A young single guy can just put his clothes in a bag and takes the next boat out of town.
Vocation aside, it's got to be really hard for a middle-aged woman, who has spent most of her life in a convent, and didn't
plan to leave, to suddenly lose her home, her friends, her habits (in both meanings) and have to start an 'outside' life from scratch.
How many of them will get another job in nursing/teaching if they had been hired
because they were nuns?
On the other hand, if the Church is
trying to discourage women from taking up a vocation,
Is there a lot of money to be made in selling off convent lands?
