Unfortunately people do not change. Look at our history, i fear that it's only a matter of time when we will see another hitler in disguise, but this time this will not be the jews that will be the target but muslims. You can feel populism all over the Europe, (i am from EU) every month right wing parties getting stronger and stronger, nationalism and populism EVERYWHERE. Only 30 thousand votes saved Austria from radical right wing president. Look at US also, political correctness in really excessive levels and not speaking about things made Trump so popular.
There is a problem with education also, we should teach our kids what populism and nationalism is, what are the consequences of radical nationalism.

We are a long way from the Middle Ages; things do change quite a bit. Look at civil rights in the U.S.: Two generations ago, women needed their husbands permission to get a job, and were only allowed in teaching and nursing for the most part. Look at the spread of democracy.
I just hope that trend you are talking about will keep up but...
I know someone that took part in World War II, he is alive still, this was not a long time ago, we are far from change my friend. Then look rwanda, somalia, balkans now middle east, north africa etc.
I guess the changes happen too slow for a single person to notice within a span of single generation. So I guess I'll have to die in hopes that I have done my duty to change the world for the better and the next generation will carry the torch for me.
