Einheitsfrontlied, https://www.youtube.com/watch?v=RhdcdZkiKRI&t=0
(Especially the 3rd verse, translated to english): "And just because he's a worker No class can free him but his own The emancipation of the working class Is the task of the worker alonе"
Everything starts to make more sense if you imagine what you might do as a billionaire capitalist: Imagine you are an automotive tycoon and progressives keep trying to make it harder for people to drive and own cars which in turn may reduce the demand for cars which could cost you and buddies billions in the long run! Save lives? You don't know anything about traffic engineering and your yes men assure you that cars are perfectly safe (and when they aren't it is clearly the victims fault)... All you know is, your wealth is under attack! So you use the lobbyists, politicians and capitalist propaganda outlets (privately owned news media) to attack the issue, to defend your wealth. In turn, by sheer volume of disinformation and propaganda, you turn the public against their own interests and protect your wealth.
Sadly, that is exactly the state of things. Working class stiffs are incredibly susceptible to propaganda and disinformation (if they weren't then companies wouldn't spend billions every year on advertising)
