The end of peasantry was
long before the rise of corporate, industrialised agriculture.
Like so many human activities, fashions, and innovations, the reduction in numbers required to work the land started off providing a benefit and ultimately went much too far. Looking at the destruction such as algal blooms in countless water courses from over fertilisation, steady soil erosion, loss of wild flora and fauna caused by industrialised agriculture and the colossal fields with a single crop, as far as the eye can see in every direction, it's hard to call it progress. It's change. Milk in shops is older than it was, homogenisation allows older milk to pass without notice. It's not progress, and hasn't been for quite some considerable time.
We have large, pretty, consistent fruit and vegetables, but there's been a 50% decline in nutrient content since the war, and a similar decline in taste -- frequently replaced by sugars. We've hugely increased systemic risk from use of monocrops as all it takes is a single virulent disease to put the entire world's production at risk -- see bananas.
Even the productivity gains are overstated. On the old mixed, family farm the raw individual crop productivity was far lower, but the chickens, pigs and plants overlapped such that the waste of one provided food or fertiliser for the others, the animals provided some degree of pest control, and as a whole the productivity was far better than usually assumed.
Industrialisation begets simplification, begets monoculture, for the sake of profit not progress.
