Interesting that adjusted for inflation however, writing pays roughly what it does in the mid 1990s per the article.
That's a little surprising.
It's also probably a more competitive industry however, and the median pay (which is what's measured) doesn't account for the best writers probably doing better than ever. And then maybe more part time people trying to break into the field but not getting much.
If there's a pretty large middle ground buoyed by union pay scales and contracts, then both ends (high/low) will not really be accounted for in the statistics.
