Maybe we just care about different things, but I've been voting for progressives for decades and can't point to much of anything I've seen fixed. If anything, I've watched the world at large and our politics get worse.
I still think there's some value in voting (see the above re: choosing the enemy we will face), but I think it's a mistake to expect or wait for politicians to save us. We have to build a better world for ourselves and take care of each other in the places and ways that we can without waiting for an invitation or asking permission.
