This is heartening to hear, but when you think about it, isn't it true that the next generation is also likely to get stuck up (and possibly exploit) some social or economic (or political) issue, and 60 years from now we can say the same for them (that they're dying out and everything will be cool)? Or do you think that we're reaching a point where basically everyone is relatively reasonable about everything and society will be overall better? I feel like you can argue for both, but in the latter's defense, life 50 or 100 years ago was a LOT worse than it is now, for everyone. Perhaps progress really can't be stopped, and maybe we're almost at the "finish" line. That said, come new technologies and ideas/concepts (such as transhumanism or augmentation), there are likely to be new groups of people that will be persecuted and exploited by our own, supposedly liberal generation.
I think it's hard for anyone to say anything authoritative about the subject as it relies on history that hasn't been written yet. I think we can say that the Baby Boomers were a demographic anomaly and that any opinions formed and reinforced through mass media are going to have a tough time maintaining market share against opinions and ideas that self-generate organically. The modern Republican party is an anomaly. Once the generation that has been indoctrinated into an ideology that runs contrary to their interests have died out, there will be no one to replace them. It isn't so much about what people believe, it's about what they've been convinced to believe.
You're right about the anomaly part, and I really hope what you say holds true in the future. Nevertheless, we won't have a perfect world, but hopefully things will get better.
