One of the biggest meat product companies in Germany (Rügenwalder) started making more revenue from their vegetarian/vegan products than the meat based ones
On the other hand, this whole argument rests on double standards - the loss of jobs due to the industrialisation of agriculture is not used as an argument against it - more as an argument for it (efficiency discourse). Veganism as a job killer (lol) could thus be seen as progress in ...eh... "societal efficiency" (totally not Overseer Barstow talking...).
It was meant as a joke since that tends to be one of the first solutions proposed to all the "But think of the oil jobs!" people when they vote against renewables when the truth is they just don't want to put any personal effort into making the world a better place, they just want the status quo, so they find some convoluted excuse why that wouldn't work, or why they shouldn't have to, or why the oil industry is actually good.
I wouldn't call the average meat industry worker an oppressor. It's a highly exploitative and traumatizing line of work that preys on the desperate a lot of the time.
