This is a sign of the times. It could be representative of moral and social decay, or it could be as a result of brain-washing and distraction by design, eg capitalism, and its henchmen, consumerism and advertising, constantly bombarding the senses and messing with people's heads. Or it is purely emblematic of the distribution of wealth in today's world, where so many have so little next to so few who have so much.
It's probably all three. Today, getting a simple bargain can almost turn into a life and death struggle. Sad.
