Well, I do think men play a big role too, but I want to start the idea off with one aspect ...
First, I think the core of a lot of the problems in the world has to do with simple integrity. But our system so thoroughly rewards a lack of integrity. In fact, the lack of integrity has gotten so far out of hand that we have to have mountains of laws to cover all of the possible known "bad things" and then some things just aren't bad enough to make a law about, so it just becomes a problem that becomes accepted as "normal".
My impression is that many women appear to crave "the bad boy".
What would happen if the message was clear that women craved integrity above all else? Would the average integrity of men rise? Significantly?
Of course, the same can be applied for what men seek in women and then there is the whole gay/lesbian space. But I think the biggest impact would be with what women find desirable in men.
... and to kick it all off .... what if there was an article in Cosmo (does that mag still exist?) that said something like "research at johns hopkins university shows that woman have nearly twice as many orgasms with men that they think have high integrity."
(if you think this is crazy,
you should hear the rest of the stuff the voices in my head keep going on and on about)
