Here we have a developer effectively looking to pay below market rates for artists, and then unsurprisingly not finding many good artists willing to do that long term. Not a judgment on my part, just saying that he's looking to keep the art budget to an absolute minimum.
Instead if it was an artist defending his choice to make relatively simple games because he just can't find good developers willing to work for cheap for long enough to complete a project.
The line that stood out me in this context:
I can't stress this enough: Finding talented, reliable, reasonably priced freelancers is HARD. Cherish them when you find them.
If the context of the discussion was about developers instead of artists, how would HackerNews feel about someone lamenting the fact that they can't get any "affordable" developers to work on their projects?
Also, as an aside:
The key problem here is that, when most people say, "Your art looks bad," what they mean is, "I want art that is good." They mean, "I want AAA-quality art." And I can't make that. Not even close.
That seems like a pretty big strawman to me. There is a large grey area between "crap" and "AAA-quality".
