I've been thinking of making a Khan Academy style video explaining the rolls and dangers of unions. People retain ideas best when they're put into a kind of narrative (historical, or theoretical/hypothetical). I need narratives like this to explain the potential danger of unions. I really want to highlight how unions can be fully deserving of the term monopoly.

The following video provides such a narrative.

I am not 100% anti-union; I just want the potential danger of unions to become common knowledge. I'd also like an Objectivist-ish understanding of the purpose/roll/value of unions. Are there ways those purposes/rolls/values can be filled without unions. Narratives (historical, or theoretical/hypothetical) for this would also be good.

Another thing...I prefer that language be kept clean and tones level. Please understand that if you make a claim and I question it, then I'm not trying to attack you personally; I'm trying to understand you. If someone (he doesn't know who he is) starts trolling please ignore him and stay on topic. I'd really appreciate it.

Now on to the rolls and dangers of unions.
