I think there's something in the air, too, similar to what Adam Curtis describes in his documentary "Hypernormalisation", which he defines as that sense of unreality where everyone knows the systems underpinning society are crumbling, yet collectively pretend they’re not. Politicians and citizens alike resign themselves to maintaining the pretense of a functioning society.
"We live in a world where the powerful deceive us. We know they lie, they know we know they lie, they don’t care. We say we care, but we do nothing. And nothing ever changes. It’s normal. Welcome to the post-truth world."
Curtis looked at the fall of the Soviet Union, but there are parallels with what's happening in America today.
Also, don't apologise for having optimism. Maintaining hope that thing can get better is a sine qua non for actually materially improving our situation.
