This has actually happened here and there with public works projects that were eventually abandoned. California's high-speed rail line actually went down this road.
Sure, and that's bad enough but at least there's usually some rationale (even if exaggerated) why it's beneficial to the public at large. Creates jobs, stimulates the local economy, improves local infrastructure, whatever.
What they're arguing is more akin to "Aunt Bessie makes these ugly crafts and sells them on Etsy, and she deserves $50 each because muh CrEaToRs and muh LiViNg WaGe." Which is complete bullshit. It's been said countless times - the RPG industry is over-saturated with indie creators and their shitty heartbreakers. If you produce garbage, don't expect people to pay the same price as if it came from a professional game company. And if you want a guaranteed salary, don't try to run a solo business in an already-crowded field.
Mod says: "Creating games is a job like any other. [They] don't do it just for fun, they do it because that's where their skills or training have taken them." Okay, so if their skills and training are so great, why not go work for WOTC or the other big names? Maybe they're not so good after all? I think a lot of these indie creators must either be hopelessly naive, or complete narcissists, to think that they possess all the necessary skills in game design, mechanics, balance, play-testing, writing, layout, marketing, etc., to compete with that industry. Gee, it's almost like it takes a whole team of professionals with varied skills to make a professional product worth a professional price!
We see this more and more with the "creative" industries, and people need to accept reality. Just because modern technology makes it easy to "be creative" and to disseminate your work, it doesn't mean your work is good - or worth the $20 you're asking for it. That goes for art, music, writing, games, videos, homemade crafts, and all the other garbage you see people peddling online. 99% of it is shit, plain and simple. For the most part, if they had any talent at all they'd already be successful in that career with or without the internet.
