This right here: "None of our problems are going to be, or have ever been solved in one dramatic action." is a really big problem, you hit the nail on the head with that one. The addendum to that problem is that for decades, perhaps even already centuries, but very noticable in the last few generations, popular western media has pushed forward the idea of the single hero that defeats the evil top villain, which leads to immediate progress. People stopped realizing that change, REAL CHANGE takes a looooong time and a loooooot of effort by a loooooot of people. Captain America didn't punch Hitler and all of a sudden World War 2 was over, it took thousands upon thousands of brave people sacrificing themselves. Big problems need big solutions, and big solutions get made with little steps. Climate change won't be solved in one legislature, but any step in the right direction is a good step. And so many other things take time, effort, and patience.

I wanna add to this, but not even defeating Hitler defeated fascism and nazism (and i say that as a german).

It took a lot to make sure it wouldnt happen ten years down the line. And still it is very unperfect.

Defeating Hitler just set the nazis back but that kind of destructive ideologies still looms around.

Apathy just gives those more freedom, because a lot of people arent immediate target and do not notice.
