There is a way to fix it. For them to admit they have a problem, en masse, and then take responsibility for it, en masse.
Which is why the other obvious part of that solution is to do whatever the hell we need to do in spite of their ignorance and the systems we all built around it. We have all -- one way or another -- been coerced or brainwashed into a system that anyone will admit is completely fucked up. No reason to be in feelings about something so straight forward.
Lonely dissent is a scary business. Someone always has to start first, and people most often don't like to be - or feel - different. Can't be a celebrity, either: people start to think funny when it comes to someone on the pedestal - as if their personal ideal has been broken and not worthy of regarding any longer. I believe this happened to Lance Armstrong after he admitted taking... some sort of drugs that enhanced his performance.
Humanity has to evolve. Besides: most people are doing whatever they want, except they're being stupid about it.
Evolution, as we have already learned, is a very slow process. More than that, "has to" doesn't equate to "will". It's not to say that humanity has grim future - it's to say that it won't happen unless required actions are taken, and maybe, for us, those actions are spreading knowledge to reveal and abolish ignorance, even if a step at a time. "Us", in this case, being not a sort of the elite knowledgeable, but any person who knows something others don't. From what I've learned so far, this is simply not true. Doing whatever you want is a privilege for a human being, not a common way. We're all controlled by fears and instincts most of the time, and even the most knowledgeable and resilient of us can last for so long at a time before needing to rest. Most often, we abide by the unrecognized laws of our subconscious which dictates how we react to this or that without us having to spend time and effort figuring the situation out consciously. It is why many people spend years of their lives in an office instead of pursuing their passions, whatever those are: we're all afraid of being misunderstood ("You have a wonderful job which pays for incredible luxury - what's not to like?!"), of being alienated from the tribe we're in ("If that loony is going to quit his job, we're done: that would be a step too crazy") or of being unloved or hated. For all our progress in science and philosophy, we're still mostly animals. It doesn't make us better or worse, but recognizing this fact whenever we work with other humans - and ourselves as we introspect - makes those who do wiser to the circumstances.most people are doing whatever they want
