They are and parents are the enablers. Give the baby whatever it takes to keep him/her from whining.
It's more than just babies. I do think it's become a serious issue with people. One reason may be we have overall become so isolated in how we exist that it seems to be harder and harder for people to function normally in interactions with others. There's little sense of community, or common tie amongst people and when there is no feeling of community, there's also litle feeling of respect or kindness in how people treat others they don't know. Everyone is, at that point, an outsider.
