There have always been problems in the US and elsewhere. It's a continual fight. Saying "woe is us, it's all rotten, we can't do anything" is capitulating in the worst sort of way to those who would take away our rights.
"Those politicians are all the same, there's no point in voting or being politically active, it's all going to hell, etc."
It's so not true, and it's just the kind of disempowering disregard for one's own agency that anyone who's greedy for power would love to hear. Man, when I hear that shit now, I just want to shake those people and say, "YOU'RE THE PROBLEM!!"
You're right, it is a continual fight. It never ends. There's no final set of laws or behaviors we're going for. The process is what matters.
