After society made the break towards post-modernity, it remained a highly developed society technologically, but as far as family structures, values, morals, political correctness, it definitely changed. You begin to see the fragmentation of family life and the strain it causes all involved. Selfishness, greed, and self-worth seem to be the tones and attitudes. The presence of media has gone from being an exciting tool to becoming a corruptive one. There are arguments of too much information.
People know too much or think that they do.
Not only is this creating cockiness among people but also I feel that personal development is actually on the decline. Modernism has spoiled society and thus creating postmodernism which is more so an effect than a development.
