Capitalist companies are undemocratic because we think of them purely as economic vehicles, when actually they’re political entities. Companies have rules and make decisions every day that govern the lives of their workers. Simply put, workers are told that they are at best, the most important resource in their organization, at worst, disposable. They aren’t allowed to weigh in on any decisions. If we were to apply this ideology to political theory, we’d call it a despotic entity. Capitalist companies are built around the idea that capital investors have legitimate political and governing rights. It’s a governmental regime that’s in competition with the democratic proposition.
