There are things going wrong now, but to suggest there’s some golden incorruptible past we’ve strayed from is ahistorical. Serving the people? The good old boys network was just how things worked!
Democratic government has always - to a greater or lesser extent - had to fight against the demons of human nature.
This is not to imply we can be complacent, but we shouldn’t collapse into despondency either. There are good people fighting (metaphorically) the good fight just as there always have been. They need our support.
