Yes this definitely holds true more for creative writing (like novels) than articles or blogging. So far. A good cover band can make a modest living at music, but most doing original music are struggling or have day jobs.
The idea that creative works have no real value and everything should be free is prevalent now. How many of us pay to use stock photos on our stories? Why would we when UnSplash provides excellent quality photos for free? As long as people are giving quality stuff away, few will be buying.
Somehow, creative poeple will have to figure out how to make money from their creativity again. If that means personal patronage, multiple income sources, refusing to give work away for free, or things I can’t even imagine, is still undetermined. In them mean time, artists will continue to struggle financially.
