now it seems people's freedom and reason is being curtailed by media/power interests.

That is a very interesting observation. I believe that people's freedom and reason are being curtailed, mostly as a process of Postmodernism (the era after Modernism). In my next post, I will write more about his.

we are at end of an age, where spirituality is coming back because philosophy and science has not managed to answer the purpose of living, seems more to it than just material comfort.

That's what I find interesting as well. Part of Nietzsche's critique of Modernism is that Reason and Science alone will not give us a purpose of living. It would lead to the "Death of God" - due to Reason people will find religion unbelievable. How should we deal with this, now that God does not give us a reason for living anymore? Nietzsche predicts an era of nihilism. This is an era in which people feel purposeless, and have no personal values. Instead, people will look for comfort in the herd, have no will power, and fool themselves in believing that their lives are magnificent. He calls these type of people "the Last Man". Nietzsche advises us to live the way of "the Overman" (Übermensch) to create our own values and purpose in life.
