My personal beliefs were shaped more by experience and by watching the news when I was young: images of angelic-looking college students in Mississippi crying like the world was ending because black people were being allowed on their campus; the slow mounting horror of Vietnam on the evening news every night; sitting with my parents in front of the TV and being appalled at the way the Chicago police were treating the protesters during the '68 Democratic convention. Being eyed with suspicion because of my age and the way I wore my hair.

I'm not sure I can name a kind of story that wouldn't work in comics form. It's words and images, and we've been telling all kinds of stories with that combination since theatre was invented thousands of years ago.

One of the things I really worry about is that if you don't see middle class wage growth, if you don't see the economy in certain areas of the country, the middle part of the country, starting to come back in the same way that it's doing especially well, let's say, in California or New York, then people are going to become politically frustrated.

There is a need for more economic growth, for more job growth. But there is a need in some people for them to recognize that they have a role in making these problems better. And we can't - we can't ignore that.

I can't blame anyone for being pessimistic when they look around, after all the blood spilled and energy spent to gain ground for working people in the past, and see it all happening again. I wasn't pointing a finger when I wrote the book, but sometimes the message is there even when you aren't actively trying to be the messenger.

I'd forgotten how challenging comics can be until I started working on Ropes. Yes, you're restricted by the boundaries of the page, but we all work within technical limitations of some kind.

The idea wasn't to make a direct political statement since the current economic collapse hadn't begun when we started on the book. The parallels I'm most interested in are the ways that human nature never changes, no matter how far back in time you look.
