Ag. can't just be about profit. There's a dimension which is national-strategic interest. Food security, the domestic food economy is important.
It is my understanding that a lot of the US ag. sector is making inputs for processing for corn oil, fructose, ethanol, and for exports to markets which in turn target american ag, selling e.g. beef back to the US, fattened on US Soy.
It's a complex web. I don't want US farmers going broke, any more than I want Australian farmers going broke (where I live)
So getting this right, fixing farming sector security, is important.

Awesome concept: ergonomics and/or posture monitoring is a market opportunity for heavy users.
