It is not only in the entertainment industry that such power play exist. In virtually all levels of society, regardless of country, culture or religion, power play exist. This is samsara. People take advantage of people, animals, religion and what not to get what they want, hoping to get some kind of happiness; which in reality are just some relieve from their suffering. Because of the ego and the resultant selfishness, others' suffering is disregarded.
Rapes, robberies, frauds, lies, cheating, covering etc are all manifestations of this selfish minds. That is where the Dharma can cure us of this.
