Too many things. But the outstanding thing is the nature of politics and politicians.
At one time, politics was an honorable profession - when you were selected to represent people you did right by them and held your head up proudly. You did this with an altruistic attitude and asked little in return (i.e. payment). You were often a ‘leader’ and who deserved respect; you could tell your children this is a person to emulate.
Take look today and tell me of an individual in public office that you would tell your children to be like.
You and I should be alive in the best of times. Instead, things are getting worse.
