It's partly because we have lost the effect of "Shame". And we, the
people, allowed it to happen. It starts in school, or at home with
young children, who are protected from natural consequences by parents.
This is then exacerbated by teachers, who are not "allowed" to apply
natural consequences, and the child never learns.
A bit simplistic, but still true...
Incidentally, this began in MY generation, caused by my parents
generation, in the "free love" era.
Nothing's free, and now, quoting a famous (undeservedly) pastor, "the
chickens are coming home to roost".
