Not sure how well this will work but the idea just popped into my head.
When I was single, in Yeshiva full time and college part time I was approached by a Yeshiva and asked to teach for 45 minutes a day. (The principal had already checked to make sure I was legally qualified.)
Although I was paid the same amount as other teachers my expenses were minimal (probably $10 a week) and I would have taken the job for a mere fraction of what they offered. I do feel that my experience as a teacher made me into a better parent (ok, ok at the expense of some one else’s kids…).
Here’s the idea-
What if the yeshivas and seminaries would encourage their students to volunteer (or work for a smaller paycheck) for a year or two after high school/ seminary/ Israel before they get married. It doesn’t even have to be teaching it could be cooking, cleaning or even making sure the lights and air-conditioning/ heating is turned off every night.
