Spoiled for size:
I find it ironic that you, a libertarian, are pointing out the threat of a Brave New World style dystopia. The Western world's entertainment industry is an almost exclusively
private sector. Its uncontrollable growth in prosperous countries is very much a feature of capitalism, not the result of any kind of state intervention. In fact, I can't imagine any concrete way to curtail it that doesn't involve giving the government even more control over our lives.
