I’m not sure all of the listed leaders share equal blame.
They are all politicians so they need to raise money and court voters.
Some on your list only care about themselves and their core constituencies.
Others appear to have an inclusive vision of human dignity and prosperity and act upon it.
Responsible citizenship is about learning to tell the difference. Failing to make wise choices means the “devils" win.
In a democracy politicians are a reflection of the voters that choose them.
My key question is what are we doing to educate ourselves so we can vote, advocate, and live responsibly?
