They aren't busy because of work. They are busy because they have three soccer games per child to go to. And they don't vote because life is good and they are apathetic - they don't see their vote affecting their everyday lives. People vote in South America because democracy hangs in the balance every day, if not in their country, then the one next to it. We haven't had that kind of insecurity since the Civil War. See who does vote - older people. They are not instant gratification oriented and can see the long-term connection between what they do at the polls and the state of the country or their locality. Non voters show up at city hall when they don't like the outcome of a particular issue, but when asked if they voted in the last local election they almost universally say "no".
