Yes, modern culture is destroying moral values and any semblance of a functioning society. Modernity shows that change is not always better and new values are not necessarily superior to the old ones. As OP said, single-parenthood is epidemic, drug and alcohol use is unprecedented, there is absolutely no respect for authority and what's happening is a complete meltdown of moral values.
People try to show that modern society is more tolerant than it used to be, but again, this isn't true - the witch hunt is still going strong, it's just that the victims are now the oppressors and the oppressors are now the victims. People show, how we've become tolerant of sexual minorities, yet do not mention how intolerant we've become of those who do not agree with liberal sexual values. Liberals watch with glee as conservatives are vilified and demonized as backwards and supposedly bigoted. There is immense ideological pressure to agree with modern liberal values and any sort of dissent is classified as xenophobia, racism, homophobia, bigotry or whatever.
Drug and alcohol use is unprecedented. There is nothing more disgusting to see a drunk girl - a picture that would have been unimaginable in more refined past eras. Binge drinking was a phenomena associated with the underclass, to whom drunkenness was the only escape from poverty - yet now, binge drinking is no the de facto recreation of everybody, both the poor, the middle and the rich. These days, people will give you strange looks if you do not dull your senses with alcohol and weed.
Families have completely been disintegrated. Single-parenthood is epidemic and the government is doing all it can to damage the traditional family even more, by rewarding sexual indulgence and by perverting the marital institution by legalizing gay marriage - this sends the implicit message that marriage exists only for the satisfaction of your carnal desires, not for unity, growth and sustainability or bonds deeper than mere sexual desire. The complete absence of any sort of sexual morality has lead to a major increase of STD-s, illegitimate children, broken families and has facilitated a culture completely obsessed with instant gratification.
Deviant behavior and poor lifestyle choices are not only encouraged by the current system, but actually rewarded. Practice has shown that if you have a stable relationship with a child on the way and you need larger housing - then the local council will send you right to the bottom of the list. However, if you are a single mother who has 5 different children with 5 different men - the the local council will reward you with a mansion. The implicit message is clear - live a carefree life full of sexual indulgence and irresponsibility and you'll be rewarded with free money in the form of benefits and large housing, complements of the tax payer.
Educational standards have also largely decreased. We spend more on education than ever before and the results are horrifying. With ever decreasing standards, this problem will become even more prevalent.
All this is topped with low fertility where we have to bring in third world immigrants who would have children for us. The average white european is more likely to not have children, more likely to divorce, more likely to abort their pregnancies and more likely to have less children than the third world immigrant counterparts. This is the result of rapid individualism, where children are seen as an impediment to personal happiness rather than something intrinsically valuable of its own.
Modern culture is destroying Europe. Darwinian selection, however, is punishing us accordingly - the conservatives and the religious will simply outbreed the decadent liberals and that will be the end of it. The future looks grim and Eurabia is on the horizon.
