DY: So look what was different 40 years ago that is no longer true now and was not true in pre-war europe, and you will have your answer.
I think every generation has its’ nisayon and its’ yetzer hara, and every generation has the imperative to withstand that nisayon and yetzer hara. It is a young adult’s obligation to choose the right path, and parents’ and educators’ obligation to make the choice of “uvacharta vachaim” as pleasant and rewarding as possible.
If I had to offer an opinion of today’s nisayon, I would say it’s the double edged sword of the influence of an ever increasingly immoral society (both in middos and kedusha), with the high pressure lifestyles we live which make it very challenging to fortify our children against that influence.
