I note the word ‘Wants’
Wants indicates a firm desire to. A great many of us want to do many things and go to many places but are unable to for one reason or another.
There is a great pressure on parents to send their girls to a seminary in Israel but I believe those with the right hashkofo and attitide and respect to their parents would fully understand that ‘Wants’ is not the way to go about things.
There are seminaries all over Europe whose fees are substantially less than $20,000 more like half that. Many girls from the US go to these seminaries. Therfore whilst I hear your worries I would rather sit down and talk to the girl in a mature manner explaining the cost implications and other options available.
At the same time it is about time schools stop preaching to the girls that a year in Israel is a must. These young impressionable girls leave school in the belief that without going to Israel their future is doomed!
