Most problems are best solved privately, not through government. There's a problem of discourtesy in the world, which is best handled through social norms, which are indispensable. But you wouldn't want the government to be mandating courtesy.

Groups become more extreme and entrenched in their beliefs and polarized from others when members only exchange information that reinforces their views and filter out all else or never learn of alternatives. Thus they narrow their options, and magnify each other's prejudices and misconceptions. This trend leads to blind spots in decision making and to extreme behavior, even terrorism.

Even though Star Wars is easily read as feminist for its time - and even for now, with Princess Leia's role - people wouldn't make a movie like that in 2016, where the guys are mostly the tough ones, and the women aren't in positions of authority.

I talked to George Lucas once, not about Star Wars. Everyone wants to talk to him about Star Wars, and I didn't want to be one of those people. In person - at least on this occasion - he wasn't effervescent and giddy, as the Star Wars movies are. He's more focused.

For the Sanders supporters, there's a thought that the people who are well off are doing really great, and the system is systematically unfair, and that's a very deeply felt and serious objection to the current situation.

Star Wars may be kind of a cartoon, but the original trilogy depicts a political paralysis which breeds an interest in a strong leader who will make a significant break with the past. And Hillary Clinton is a person - whether you like it or not - of extraordinary experience. I don't know if we ever had a presidential candidate with that level of political experience. There's no learning curve for her. And that, in some periods, would be a huge plus. In the end, I think it will be a significant plus for her now.

If you take anything that succeeded, just imagine it succeeding 10 years before or 10 years after, you could almost always make, with the same plausibility, the "it fit the times" argument.
