Candy613 made a great point, a year in Eretz Yisrael is incomparable, and leaves a lasting impression. If it is too expensive, perhaps American sems organise trips out there so some young women can experience Israel if they have not done so before.
Parents should not be pressurised into paying for any sort of fad, a year abroad, fancy car or over the top wedding, they also need to show unity in number and not pressurise each other into comparing simchas and spending. It does happen and not just among kids!!
