"In my opinion it also has to do with the disintegration of the Jewish community"
Thank you for your observations.
Remember, I am from Memphis, and I never observed strong orthodoxy that I see only in movies.
Some of my best friends were Jewish. One was a great interior designer, and put on the best New Years eve parties that I ever visited. The nearest synagogue was only a few blocks away from his home.
The vicinity of the synagogue is a major decision in where an orthodox jew lives.
We are not supposed to drive on the Sabbath so live close enough to walk there.
