Interesting piece here from FiveThirtyEight, comparing the upcoming science march with other collective action protests, especially the "tractors on the mall" protests. I remember them well. This was the time period when I moved from directives to programs, specifically the "normal crop acreage" concept (i.e., a base for the whole farm rather than crop specific, intended to give more flexibility to farmers) and a disaster payments program which was, in effect, competing with crop insurance to see which approach would become the one for the future (crop insurance won over the next 15 years).
It's significant, I think, that the 538 post links to the American Agriculture Movement website; the AAM was the organization behind the tractor cades, but in fact the website is defunct, with nothing updated since 2015. While commodity prices are down and have been down for the last few years, the farmers who are left aren't in as bad shape as they were at the end of the 70's.
