This is one of my favorite topics to study. I think the Block chain does not in itself eradicate poverty, but creates a healthy and clean environment for honest human beings to enter the field and achieve social justice around the world. But we must not forget that just as bitcoin can eradicate poverty, it can cause chaos in the world if left unchecked, so governments better deal with it peacefully and avoid fighting the Block chain revolution.
While I believe that cryptocurrencies will give more people access to financial products, and that may help to lift some out of poverty, they won't eradicate poverty completely.

Also it is impossible for "everyone" to be "rich". Think about it if everyone was rich
a can of soda or bottle of water would be $100 for example
