This particular protest might be an internal German matter, but distribution of wealth is not. The message should reach as broad an audience as possible.
Us who have zero influence on German government policy? Why does it matter what language we discuss it in? What matters is persuading the people that can influence German government policy, and one does not influence them in English.
My guess: it refers to the 'Fridays for Future' movement. More or less arguing that caring about the climate does not matter if the farmers go bankrupt.
Farmers go bankrupt because organized and technified farming displace them. I have seen all along in-develoopment countries, farmers trying to farm manually as they ancestors did, getting outmatched by Jhon Deere and complaining about the system, instead of modernizing
I'd think this is a purely internal German matter.
