I saw that movie in 1976, and nothing much has changed. Half the people don't even bother to vote or try to stay informed about anything. Most of the rest get their information in 30 second manipulative sound bites, a nice way to say lies, while waiting for their tv show to come back on.
I'm not mad anymore, I'm retired, so's my wife. We just collect our Social Security payments and hope for the best.
I watch the news from Germany and Japan mostly. Interesting perspectives. This world is wacked out now, but has been for as long as recorded history. It's hard to know who to blame.
Pogo said "I have met the enemy, and he is us". That's about right.
