I don't think I agree with this, I know I became more aware and more empathetic after I was able to improve my financial situation. I believe that a lot more people do care or would care than you think, it's just that their energy and focus is on survival and trying to live in a world where you're told spending=happiness.
Maybe it's naive but I have a fair bit of faith in people doing the right thing when given a chance and a way to.
If it exists I haven't found it
