Agriculture is a No. 1 on a list of "useless" college degrees?

I remember our geography textbooks in sec school, where agriculture was classified as a 'primary' industry. It gives us the impression that it is low-paying and not lucrative. While that is true in certain periods of history and is certainly true in the past 3 decades, it is beginning to change, and should continue to do so in the next decade or two. 

The average age of farmers in the US is now 58 years, in Japan it's 67 years. More than one third of European farmers are older than 65 – technically retired. Less than 5% of farmers in analysed (by IFAMA) countries are younger than 35-years-old! All OECD countries show similar trends.

And just for LoL from this article below:
"Aside from trying to stem the graying of America's farmers and ranchers, her mission is fueled by a recent blog posting that put agriculture at No. 1 on a list of "useless" college degrees."
