Reminding just how bloody Union history was is kind of a heretical thing to mention here.
The CEO class thinks their lives matter more than the masses. But talking about history or giving a nudge that violence did work certainly makes the CEO fellators come out en masse.
The reason why we're seeing firebombing, shooting, arson, etc is because the public feels they have absolutely no legal way for grievances. And with the NLRB at 2/5 and no quorum, and inequality so extreme, its true. So its illegal. And violence absolutely does work - just you cant ever admit it. Violence is how the USA got the NLRB, and a decent legal process for grievances.
I still look at unions and companies, and the real problem is still the unresolved split between the 2. And the only counter to massive resources and money is violence. And we're already seeing it. Only good solution is worker cooperatives. It the only path that solves the arbitrary dichotomy of owner/worker, democracy in the workplace, and allays feelings powerlesness leading to mass shows of violence.
