Civilized folk have gotten better. The behavior changes that were wrought by our society during its peak period from 1890s through the 1960s were key to the progress made during those years, and the three decades following. Those behavior changes have been largely undone by an academic system that has foisted learned helplessness on the kids, and banned critical thought from the classroom. Rudeness is tolerated rather than expelled.
The predator ape base has been encouraged to destroy the achievements it could never accomplish on its own.
