Lobbying groups, putting out press releases, claiming victory...
Here's some things you won't find in any of the documents, including the PDFs at the bottom: community gardens, local food, farmers markets, grass fed, free range... Because agribusiness doesn't make money with those.
Just because you might like the results doesn't mean they aren't corrupt as hell
Agribusiness absolutely makes money off of those. In fact they had a hilariously easy time adapting to the consumer trend because all they had to do to label a cow “free range” or “grass fed” was change the finishing stage to a lower density configuration instead of those abominable feed lots you see along highways. The first two stages, rearing and pasturing, didn’t change because they were already “free range” and “grass fed”. Half of the farmland in the US is pastureland and leaving animals in the field to eat grass was always the cheapest way to rear and grow them. They only really get fed corn and other food at the end to fatten them up for human consumption.
The dirty not-so-secret is that free range/grass fed cows eat almost the exact same diet as regular cows, they just eat a little more grass because they’re in the field more during finishing. They’re still walking up to troughs of feed, because otherwise the beef would be unpalatable and grow quite slower.
True grass fed beef is generally called “grass finished” beef and it’s unregulated so you won’t find it at a supermarket. They taste gamier and usually have a metallic tang that I quite honestly doubt would ever be very popular. The marbling is also noticeably different and less consistent. Grain finished beef became popular in the 1800s and consumers in the West have strongly preferred it since.
I’m not sure you can even find a cow in the entire world that isn’t “grass fed”. Calves need the grass for their gut microbiomes to develop properly.
This is a material win for humane treatment of animals as well as the health of the consumers who aren't eating the stress hormones of a tortured large mammal. The price difference isn't even that big. Of all the things to complain about in the meat industry, this is not top of mind in my opinion.
