The best feature of democracy is that they give an illusion of empowerment. You voted for someone put forward by a hundred thousand person organization, who maybe went on to get a job in an organization of several million people. So isn't that a government "by the people"? Yes, the real strength of democratic government is that it is good at propaganda.
In a company, where real results matter, resources are finite, and customers have alternatives, it is almost never used. This is despite the fact that most Western Europeans (and descendants) think democracy is the best form of organization ever. There's a reason for this.
This is precisely the reason that some geeks advocate turning government into a hierarchical corporate model, run by shareholder democracy - is the form of organization universally chosen when results matter
As clearly stated in that article, the US gov has weapons that are too powerful to be resisted. So we can't just stop paying them our taxes if we don't like their services. Capitalism in the US still depends on the US gov stepping in occasionally to break up monopolies when customers aren't able to choose between competing companies to give money to.
