Let's consider just music for now. Go to Soundcloud, Bandcamp, etc. and see how much music is already freely available. What percentage of those artists are able to make a living as full-time musicians? (especially when the trend is now to pay $X/mo to consume all you want)
And if income inequality increase, there will be less consumers able to consume that increased supply, further lowering the value of the supply of music. The "winners" of the situation who end up with more income do not have additional time to consume ever more greater quantities of music, while the losers have less money and potentially also less time (if they need to work more to make ends meet).
Edit: Also, given your wording of the question it seems like you aren't a producer of creative content yourself, so perhaps you aren't as directly aware of the trend I'm describing above, which has already had a serious effect upon an already difficult-to-pursue profession.
I guess I'm not as aware of the trend. My guess is that as the focus of commodities shifts from exporting intellect to exporting creativity, so, too, will the value of those contributions and the way we're exposed to them. At some point there will be a shift from the content distributors to the content creators directly, especially as artificial intelligence around curation of content gets better and better.
Are you serious? All we do outside of work is consume others' creativity.
