That would ve wonderful with regard to mental illnesses but the solution will unfortunately be a long way off.
With that said, there is a more simple solution to societal degeneracy and its simpy a return to morality, but it's not merely an acceptance and personal adherence to the Golden Rule. Society must have a high standard of morality in order to inspire and establish proactive introspection, high level of work ethic, and encourage and hold each other accountable.
Moral degeneracy always starts with ethical compromise.
The problem is that not everyone would agree, and as of yet, there is no unifying code of ethics that is strong enough for all to adhere to with zeal philisophical//ideological/religious zeal.
Historically, we don't see very much of a pure example of a decadent people changed but nevertheless can see a profound change of mentality and practices from one worldview to another. It often comes in two phases:
1. Doctrine/Highly Charismatic Personality
2. By Legislation/Force of Arms
Obviously, force of arms is out of the question here so we're left with doctrine and legislation, . What we're left with is only. Conservatives oppose legislation fearing Progressive Communism and Liberals fear Theocracy.
So how does one transform a society without threats of violence and legel oppression? We have to debate what ethics we want to adopt for the whole.
