>>2852282>for praxisIt's not and hasn't been since firms have de-territorialized themselves. Modern unions can't exerce the same influence on firms because they fundamentally operate on different grounds : the firm exists on a global scale with intellectual and property rights, whilst unions exist on one or two sites specifically.
This means that if one firm is "overran" by a union, it can just call on its shareholders to invest more money to delocalize somewhere else. The firm isn't tied to the territory anymore.
>for an alternative social modelThe ward problem shuts off the possibility of any model based on unions working well. In short, any union will just end up maximizing its own interest rather than arriving at a collectively-defined interest which implies that the same power assymetries and self-interested allocation will pop up as in capitalist societies. Mao was correct when he distinguished between
whole-people ownership and workers ownership.
