Sorry for answering so late. I think you are very right there. Once you give a person the possibility to do good in an easy manner it will be done. We "just" have to set up a system that enables people to be rewarded more for giving than for competing. Ethereum will bring a lot of these possibilies in the form of dapps to this world. I am optimistic that we will see a change, although I don't know how it will look like exactly. And that is the interesting part for me.
