I think we can safely say bigotry and war were around at the time Anne Frank was alive.
Yes my initial thought was people are more self centric than previously, but I wonder if that is a consequence of other things in society, such as population growth and industry growth, that we simply don't know how to do things in the same way anymore. In the past, and in some current communities, families and communities were more community focussed. You still see that in some indigenous communities where it is the elders, or other family members all helping each other to raise families, and contribute. Yet for many people, myself included, live nowhere near family, and don't even know their neighbours. We have certainly lost a sense of community
I then thought about the ways in which we are not so self centric anymore. I think children are seen as people, with opinions and things to say far more today than in the 1940's. And for that matter females are seen more as people too!
whilst this society has lead to the rich getting richer and the poor getting poorer, you cant say all rich are scum. I think while there are many Donald Trumps in the world, there are also the Richard Bransons' who give back, and seek to make the world genuinely better.
Climate Change/Global warming is a tough one, as I think the majority of people do know things need to change, but unfortunately the ones who really have the ability to impact the biggest changes are not doing what needs to be done.
Thats my two cents worth anyways
