- The CPI has doubled in the last 30 years; your link doesn't mention constant dollars that I noticed.
- The line chart ends in 2011.
- The sources of fees according to the chart in your link are very concentrated in almonds, which suggests they would be heavily impacted by the ups and downs of that industry.
So, I'm not saying your assertion is false, but the most I can say about the link is that it doesn't contradict you.
