When did we Stop thinking Heaven on Earth was Possible?

Let me get this straight so we are all clear. Is the goal for everyone somehow NOT heaven on Earth here? Have you all just STOPPED thinking that was possible? Is the goal freedom from slavery of any kind? Has everyone settled for "how it is"? Thinking some things will "just never change"? LOL LOSERS. I'm sorry, my ever growing, open mind just doesn't think that way.
It's most likely not going to happen in any of our lifetimes, but people, what the F are our kids going to think about what we've let happen here? Are you that selfish? Look at how far we've came, WHY STOP? Life CAN be extended further than it currently goes. EVERY disease has a cure. There is WAY MORE good than evil in the world which means we DON'T HAVE TO LIVE IN FEAR. There IS ENOUGH food, clothing and shelter for everyone IN THE WORLD to have better than decent living conditions.
The people in charge are admitting change needs to happen while offering up two maniacs as possibilities OF that change. MADNESS! Did you actually think Bernie had a shot? If he won, do you actually think they wouldn't do everything in their power to make anything he tried to do difficult?
We won't win within this system. It has to crumble. If we don't do something fast, I'm picturing soldiers on street corners. Civil war.
I'm ready to fight. They've put the future of my children and my family at risk for way too long.
