Think about it. The Avot v'Emahot means our forefathers and foremothers. As we read this prayer, we think about what the world was like in the time of Abraham and Sara, Isaac and Rebecca, and Jacob, Rachel and Leah, and how different the world is today. They didn't have to worry about AIDS, drugs, gangs, or many of the other problems of our society. But their society also had their own share of problems.
Every society needs to be fixed in one way or another.
Tikun Olam - we need to repair our world. We need to elect responsible leaders who care about fixing the things in the world that are broken. We need people in government who are going to change things. If you don't vote and use your right to try to change things, than you have no business complaining. If you're not part of the solution, you're part of the problem.
