Have the accepted/standard morals of the average American declined or improved over the past 30 years??

Declined drastically. Any sense of morality it valued has gone out the window for many people.

yeah decline.. lack of concern and care for each other. do what makes you happy is what people believe now a days.

Declined in the younger generation id guess because theres so much lack of empathy today. Imo.

probably marginally improved, at least from my moral viewpoint.

Declined
