What is a value that will give rise to laws and customs that will allow people to be happy?

I have to write and essay on a "suggestion for a mix of regulations and values that will give rise to the laws and customs which will allow people and the planet to sustain health and happiness." I kind of have an idea about what to write, people need to value empathy, support of others and knowledge of the world around them. but i dont know if thatll be specefic enough. Any suggestions?
