You are welcome to your viewpoint of course, but IMO nothing is going to change unless it benefits the unknown that run our world.
Am I complacent- no, but I know what a losing battle looks like.
A "better future"? I think that hope vanished the day the world population passed 3 billion, and now it's just a long, slow downward spiral to the end, whatever the end may be, but IMO not good for anyone around then.
Am I cynical? Absolutely.
I only have to look outside my door to be so.
