Let's hope good for our Muslim countries. The point is, no matter how you try to justify, lewdness has a negative impact on the society as a whole. It disintegrates families and promotes spinsterhood. Youth may just get used to having relationships leading to more and more promiscuity.
Look at America for instance. Some decades back, the rate of marriages was high. Dating started becoming prominent, though the ultimate goal for dating in those days was to find a suitable partner for marriage. This goes against the Law of the Creator. He has permitted us to select and find out about the person (yes, vet them completely) and even talk to the prospective bride/groom in front of the Mahram (i.e. male relative like father, brother), but God hasn't permitted dating. Dating leads to relationships, and in fact in dating one may never know the true person (love is blind as they say; truth comes out only after marriage).
Anyways, the point is, what started as a culture of dating in America, today has developed or "progressed" into 'One Night Stands' or 'Hooking up' as New York Times columnist Charles Blow has put it. The culture of dating is dead. Now people there have become even more promiscuous, and have almost lost all forms of morality, as they accept one night stands and get their lusts out hoping for something good to happen out of it!
This is what happens when we ignore the law of our Creator. Our Muslim brothers and sisters should learn from this and satisfy our desires in the Halaal way - marriage. It has the blessings of Allah, it's pure and what comes from such a relationship is beneficial, productive and good for us and for the society.
