I used to agree with you, but I don't know if bringing people out of poverty helps them learn not to hate anymore. It's a good platitude, but it's not what I've observed here in NWA.
Ya, it isn't overnight, it is a multi generational process.
I think that most progress in society is made through the death of the previous generation and new ideas being more accepted. It is slow but crunches on over the bones of the old. And, this is why it is so important culture/society/government get in there to break the poverty cycle, break the ignorance, teach critical thinking, etc etc etc...
