Right. To add to this, in the US system:
-- the vast majority of bureaucrats with power over the average man are not elected or even subject to firing
-- we do not truly have a system of one man/one vote. the guy who writes the new york times headlines on election day literally controls at least a million votes.
-- the candidates who are dubbed "serious" by the media are not chosen at random. By any quantitative theory of political voice, that up front winnowing from 300 million to ten or so is more substantive than the election itself.
-- in the business sector, power is wielded with far more responsibility. there is a CEO and an identifiable company behind a product, which can go out of business if it displeases its customers, and which is subject to feedback on an instantaneous basis through purchases. by contrast most govt projects are products of committees, with permanent funding and diluted accountability only in the form of the 2-4 year election cycle.
in short, voting with your wallet or voting with your feet means far greater efficacy and voice than going through the ceremony of voting with a ballot.
-- Rule by an elite is inevitable. The process by which that elite is selected is everything. The US used to be much more aware of this, referring to itself as a "republic" rather than a "democracy".
-- The Chinese model is a lot easier to understand when comparing it to Apple. Should Steve Jobs choose his successor through a plebiscite in which he ostensibly has the same voice as a retail store employee hired yesterday? Or should he choose a leader who he thinks will follow his path? In the latter case legitimacy among Apple employees ultimately rests on the bottom line success of Apple, with the necessary safety valves being exit (freedom to quit) and market (revenue growth) rather than voice (noisily protesting Jobs' successor).
In the same way, most Chinese believe that Deng was the best qualified person in China to choose his successor. And legitimacy comes from continually posting solid bottom line numbers, something the US has not done for a while.
