OK, BUT, could the Lord not have any privileges he wanted with the serf girls? Who was to stop him.
Just because something could have happened (theoretically) doesn’t mean it did happen. History doesn’t support this theory.
Just my cursory reading today doing those searches proves otherwise. They had a social and economic system and it worked in its way, in some ways probably better than what we have now.
Anyone with any power can always abuse their positions if they are immoral. Happens now all the time. If anything, morality now is infinitely worse.
