The whole point was to make a clear distinction between the working-class farmer and the mega-rich, evil factory farmer. The latter loves to act like they are the former.
The real story with the farmers is that there are 3 very large farming companies responsible for more emissions than all traffic in the country combined. That's close to 10x more emissions than the whole aviation industry. These are billion euro+ sized businesses, with a huge environmental impact. They pay PR firms to paint these "small farmer" stories while they're just large industrial polluters.
The main person for the political "farmers party" has a long history of being deeply involved with these companies. She's basically their lobbyist.
Example: Van Drie Group, over 3 billion revenue last year from veal. In Dutch, but a bit more background here: https://www.groene.nl/artikel/het-merk-boer
Besides, it was just an illustrative way of saying "plenty of farmers are pretty well off". A bit silly to focus on that part of my argument instead of the actual point, which is that most Dutch people feel those big earners are the bigger problem.
Whatever measures are taken should, in my opinion at least, focus on the highly automated mass polluting bio industry and subsidize smaller, eco- and animal-friendly businesses instead.
The massive food surplus clearly leaves plenty of space to trim down a bit. The resulting CO2 decrease might even allow a few new houses to be built.
