I was having a discussion with a friend about video games, and she said, "Just imagine what we could accomplish if people took the time they invested in video games and invested it in something meaningful!"
Now, setting aside the question of what is meaningful, she makes an interesting point. Obviously, the point applies equally well to television, film, music, and entertainment in general - video games are just one kind of entertainment media among many.
So my question is this: do we have the right to devote some of our time to entertaining ourselves, when we could instead be devoting that time to fighting global warming, AIDS, violence, poverty, depression, cancer, and any other number of ills? How can we justify entertainment for as long as suffering continues to exist?
