Part of the problem, or part of the solution?

If you are not a part of the solution, then you are a part of the problem.

I think I saw this on a bumper sticker originally, but it is also a common concept. And in this I read that people should take the responsibility to work with others and communicate in order to find or work on solutions to the maximum possible, otherwise they are just contributing to allowing the problem to have that much more power over the solution.

I think this is also expressed with this quote from Albert Einstein : "The world is a dangerous place to live, not because of the people who are evil, but because of the people who don't do anything about it."
