My proposed solution is to promote education and skills in the arts. This will open up creative outlets and hobbies for individuals, which may be essential to maintaining fulfillment and satisfaction in the long-term. Alongside this, one can imagine a reinvigorated prioritization of community, social skills, family, sports, and more.
I've seen this type of comment a few times. Generally, it's not clear to me that an education in the humanities leads to better morals compared to an education in the sciences (see all the politicians, bankers, lawyers, etc. who have a humanities background -- not clear that they're as a class more moral or ethical than the engineers, physicists, etc.); clearer communication (see any number of employees in large organizations); more life fulfillment or happiness; more creativity; more community, or anything.
