I agree that climate change, equitable wealth distribution, and universal health care are possible. According to psychologists about 15% of our populaion are psychopaths who are similar to Trump. Removing the dark glasses shows us people who will stop at nothing to control others. These people have ruled humanity since we evolved, and similar animals ruled our ancestors. I don't know if there is a way to satisfy such people so the rest of us can live ethically.

You lost me at, “We only need to take off our dark glasses and be optimistic.. which means we need to get out of our comfort zone, own the problems and take real actions.”

I well remember ..debating a former sister-in-law ..that the far-left needs to take off their rose-colored glasses and acknowledge the reality of various situations. Come to learn, those ‘rose colored glasses’ were her (and friends) defence from reality…

Had she been wearing ‘dark glasses,’ that would not have provided the ‘comfort zone’ she & friends apparently sought, fearful of becoming too depressed, thus choosing to remain in a ..new age fantasy land amid their own kind.

My brother & I were Honest Atheists, apparently, too direct to handle. How bout we shed both glasses ...cept the ones needed to type letters to editors.. It's rough, organizing thinkers is far more difficult than leading the ignorant

A lot of it has to do with wealth and abundance. When humans are struggling for survival, they don't worry about other humans or the environment, they are more inclined to take things from others. When humans have some safety margin, they become more concerned about other humans and the environment.

we desperatly need to change our breeding habits, our greed and how we live.
