Assuming you're in Germany, where do you read/watch/ get your media from? I'm very interested in becoming more politically helpful in this country and creating simple messages explaining why some parties deserve your support and some absolutely don't and I don't know where Germans get there material.
I'm contacting some local parties to see how I can help and volunteer, but I'd also like to be putting out material on a YouTube or blog or discord if that was beneficial and discoverable by my neighbors and friends of friends etc.
I can't speak to that specific situation but I believe power should be held the shortest distance from the people it effects - balanced only by having more power for more people. I imagine health insurance owned and controlled by unions is less powerful than owned and controlled by the government but the distance is shorter. So ideally it would be held by a government to maximize the negotiating power essentially, but if the government is run by incompetent or immoral people (like I'd assert the CDU is) I could see union control being better.
