Bullshitters have always been with us only now they have a bigger stage.
Inferiority complexes used to abound but now narcissism seem to be more prevalent. Perhaps its the same affliction with a different response to stimuli.
But there is a definite upswing on " I gotta get mine".
I think the unhappiness gene that comes with advertized unlimited possibility that's rampant in the US has caught on in other countries. A dissatisfaction with what one has and needs more, leads to trampling over other people to get it.
