As long as the system remains as it is, nothing will change...
We are supposed to have democracy in the majority of the "civilized" countries, but what we have is a form of dictatorship: big corporations - mostly in the banking and pharmaceutical industries - are controlling the politicians and therefore the governments... They have the control over the media, "informing" the masses only on what they want...
All the facts you shared are shocking, but even more shocking is the fact that, even though it's so simple to solve the biggest problems on earth, nobody - of those who are responsible - does anything!

How can something be changed when those responsible to bring the change are those who have created it and are maintaining it...?

The biggest hope of humanity is some people and organisations that really care about humanity, they help and they fight for change...
The global expansion of the internet is giving a big power to us. It gives the opportunity to everyone to have access to information that are not controlled and/or censored by the manipullative big media...
An opportunity for everyone to have access to education which they couldn't have otherwise...
To speak up and communicate with like minded people and realise that there are many of us who think differently and who really care about humanity...

I believe the decentralised blockhain environment advances this opportunity to a whole different level... Steemit is a great example of that.
Not only it helps people like fukumineko to advance their lifestyle but it also gives the chance to people like you (and others in here) to help both practically by rewarding and also by sharing the messages of compassion, empathy and support, for creating a different and better world!
Congrats on what you are doing!
