I certainly don't expect things to turn around in my lifetime. The future I want would require radical, systemic changes, but most Americans don't want anything to radically change. That doesn't mean a majority of Americans are happy with things the way they are, not at all, but they don't want to radically change anything, despite their unhappiness. The majority of Americans want things to get better without anything fundamentally changing. I believe that's one of the definitions of insanity.
As if Americans have any control over the change. Even if they/we did want it our capitalist overlords would never allow it to happen. They only want the illusion of freedom.
