love your optimism in the face of the massive self-interest currently on show in Theresa May and the Tories, and Trump and the Republicans.
It's not really optimistic at all...I think we are headed for very dark times. This is just one symptom of the terrible situation.
I think we all know this, but I am not sure that most are really willing or able to look at what it means. They imagine perhaps tough times like post war austerity, or the "benevolent" paternalism of late 19th century liberalism.
In reality we are staring into a future, if we choose not to change the way we operate, where we will all be forced/choose to do things, and things will be done to each of us, and to our children, that would sicken and terrify if we acknowledge them.
But I do believe that if we so choose, if we use our strengths as a species, our altruism, rationalism and scientific abilities, we can make it. It will be a close run thing.
