Have you considered that this "crisis of morality" is just an artifact of right-wing politics since 1960's?
In many ways it probably is, partly as a self-inflicted wound, and partly as a political tool. Here are a few moments that might be worth mentioning:
- The realignment of the south with the Republican party comes in the 1968 election, in the aftermath of southern Democrats voting for the Civil Rights Act and the Voting Rights Act. That realignment arguably started with the election of 1912 when Teddy Roosevelt lost the Republican nomination to a much more conservative Taft. T.R. went left and founded a couple fringe parties, while Taft went right and put the party on a more conservative trajectory. Meanwhile, when FDR takes over the Democratic party, he moves it socially and economically left from where Wilson was, and into the opening left by the Republicans moving right. Anyway, the point is that the post '68 Republican party has become the defacto home for racial anxiety, Paul Ryan's more recent efforts to claim the mantel of Lincoln not withstanding. That's not a good look, even if it's a small element of the national party.
- The cluster that was Vietnam left a whole lot of folks thinking that the establishment did not have their best interests at heart, and were, as a matter of fact, profiting from conscription, death, and misery. The second Iraq war is a sequel for the next generation, minus the conscription, but complete with all of the pointless death. If all the patriotism-talk is mostly a cover for elite ambition and profit motives, then public service looks like a suckers game.
- As Reagan's deregulatory turn in the 80's threatened the business coalition with the religious right, the idea of a culture war was amplified (even as in practice it was dying down) and the world of political evangelicalism and the moral majority emerged as a cultural response and reliable coalition partners for the business community. Meanwhile, the supposedly moral figures in the evangelical movement provided a steady stream of scandals, from Jim Bakker to Ted Haggard.
- And I suppose we need to mention the ongoing crisis of child abuse in the Catholic Church, too.
The point is that some of it is real, even if self-inflicted, while some of it has been manufactured for political purposes to hold the present coalition of the religious right together with business interests.
A post-WWII vision of public morality began dying off with the Vietnam generation, and was basically buried society-wide by the mid-90s. The problem, as I see it, is that nothing has really taken its place. The idea that we shouldn't be racist, sexist, homophobic, or sexual harassers is really just an expectation that we respect other people as equals and more or less leave them alone. I don't see any emergent set of obligations toward neighbors, community, and/or country that were widespread prior to Vietnam. On the one hand, it's tempting to blame the boomers for burning it all down without leaving anything in its place, but as mentioned above they were also sold out by business interests in their parents' generation.
