Yeah... "some sort" says it all doesn't it?
It's a much deeper discussion that this topic or medium affords. But that very same system took away through various means millions of citizens' right to vote, and routinely generates situations where the will of the majority is overridden by a minority. And there's a lot more where that came from. You are given just enough power to feel in control but not enough to be in control. You have a voice but nobody really has to listen.
I grant you that, there are clearly far more freedoms in the western world in general than in China. But there's nothing better about US's system of values than say the Icelandic one (quite visibly the opposite actually). But...
It all boils down to one simple fact: the US imposes it's own views on the rest of the world via military and economic measures against anyone who doesn't comply, doesn't have anything truly of value to trade, or threatens that military and economic superiority. See Saudi Arabia, one of US's closest ally vs. China, one of US's biggest enemy. Both have the same values yet get very different ends of the stick. There's nothing making this system better other than the military and economic force behind it.
And I'll leave you with a bit of foods for thought: large scale organized crime groups also elected their leaders through "some sort of democracy", and have economic and "military" power to impose their will even over entire countries. What does this say about their system of values? Must be tip top.
