This quote is saying that if people treat each other like they are family members, then there can be hope that society will be a better place. In other words, instead of having several separate families, it is important to act as a single family. This means taking care of each other, being understanding, and treating each other with respect. If we all work together and treat each other like we are family members, then there can be hope that society will become a much healthier and more productive place.
