Plato & Democracy

I was wondering if anybody else noticed Plato's disapproval of democracy. Although it seems unfair, I can't say that the thought hasn't applied to me too. Why should everyone vote when many people are not educated enough with concern to the issues at hand? I am not trying to sound elitist...I would put myself in this category of people that are not well educated enough to make a well informed decision and vote on it. The book does say however, that this opinion was a result of the poor government of the time so I wonder what Plato would think about the modern, more controlled form of democracy that we have now. I also don't understand Plato's description of democratic minded people as "lacking in discipline, pursuing mere pleasures of the moment, indulging 'unnecessary, spendthrift' desires". Although it may be true that they are not sufficiently educated on certain matters, it does not make people uncontrollable.
