@Radical_EgoCom We *could* ensure equal shares of the means of consumption, but that would also eliminate the ability of the market to allocate scarce forms of labor! :D I leave it to you to propose an alternative method, but I'm okay with stipulating "a magic fairy does it" for the purposes of this thought experiment.
Investors *might* have a disproportionate influence at a single firm, if they decide to put all of eggs in one basket. But since everybody has equal wealth...
@Radical_EgoCom the investors would have the same power over society as a whole as the workers themselves. (And the investors would also *be* workers, either at the same firm or a different one.)
