If there is no Bourgeoisie or the government explicitally restricts the Bourgeoisie from controlling the media, who else but the proletariat would control the media?

Just because some people want to oppress others to feed their weak egos doesn't mean that all of humanity wants that. I think most people actually want to live in a society that takes care of them, and in turn will love to help out and serve society. Once it becomes the norm to look out for the collective interest instead of self serving behavior, self serving individuals will either need to learn to adapt, hide or get ostracized by society.

Human nature is not static. Human nature is reacting to the conditions they live in.
