The benefits of living OOT.
All frum Jews send their kids to the one orthodox day school. Chances are it is run by Chabad and full of Litvish, Syrian, Israeli, EuroTraditional MO, and the children of the Lubavitchers running the place.
The kids daven at school from Tehillat HaSem, and follow the Chabad luach. They go home and follow their family traditions and attend different shuls with different nusashim. BUT the community all works together to ensure there will be a vibrant school to serve all who want to attend. and they will be supported by non-frum members of the community and Federation as well.
