However, this is an era of not reading sage books. You must feel what people in this society are like. If you are poor, you will bear a grudge against those who are rich and heartless. If you are rich, you must be worried about your wealth and personal safety.
Ancient sages must have experienced such confusion in our time before trying to think about what a society should look like and what a person's heart should look like. Everyone should start from himself, and the society can be good.
Finally, I use Zhang Zai's famous words in the Song Dynasty to answer you: Make a heart for heaven and earth, make a life for the people, carry forward the past and forge ahead into the future, learn from others' strengths, and be peaceful for all generations.
