Simple Pop Culture Evaluation

Miley Cyrus, otherwise known as Hannah Montana when she was still a saint and young woman.  Now she is at the forefront of pop culture, twerking away her innocent image she had created growing up as a star of a very popular Disney show.  Think about that for a moment, shes pulled a totally 180 from how she use to be, and those who watch MTV and VH1 couldn't be anymore proud, unlike those of Disney.  She use to be the role model for young girls everywhere, including my sister, but her type of fans have likely changed, whether by personal disgust, or by protective parents who dont want their little girls to know or see what she's become.  It's a shame in a way, that a person so respect for the right reasons could still be so respected, but by i different audience and crowd of people, not to mention an opposite set of reasons.  This displays how much of pop culture today has to do with a sometimes negatively influential  idol, whether its because they twerk in front of many people on a national stage, or because they're living the high life on the popular drugs around today.  When I think about it, pop culture hasn't changed much.  Marilyn Monroe is the idol of many today for a similar reason, though the reason has really evolved from that era.  Sex sells, and its true by what Miley represents when she does her thing.  Is this what pop culture should  be though?  Is pop culture supposed to be a child star evolving to a naked woman on a wrecking ball?
