Earlier quoted context omitted.
No, it will not be filled by people with "passion", it will be filled by people with free time and economic security. We don't yet live in a world where passion is enough to motivate free content.
Nobody is going to go through the trouble of writing content they aren't passionate about if there isn't a financial incentive. As for the free time argument, people who are passionate about a subject make time for it. These people you claim are too busy just surviving to write content still find time for several hours of television/video games/other worthless use of time a day.
The people I'm talking about are either too poor to follow their passions and work for free, or have the time but have decided to channel their passion into something that might make them money.
Basically, I have a problem with this quote: "Is content that needs to be supported really that valuable? Might the world be a better place without it?" The idea that anybody who publishes anything of value would be willing and able to do it for free is just obviously wrong. The world would not be a better place if independent content were only created by a tiny portion of humanity.
