In every society, taxes and government are the lens used to focus collective social responsibility and direct actions that will benefit the society as a whole, and individually. Even in a collectivist society, some work is done to benefit a small group of individuals when it's deemed necessary by the society. And in an individualist society, effort is also undertaken to benefit the whole.

The questions you pose are good questions, but they can't be answered by this presentation. Even if you were to ask a much more "fundamental" or "simple" question, like "How much should we sacrifice for sanitation?", the answer is not clear, as it will vary by location and other criteria.

This presentation can't answer the questions, but it can cause us to ask them. Let's remember these questions and take them forward into our local communities, and try to focus more on local solutions, and less on one-size-fits-all.
