A few things to add to these posts.
We live in a representative republic, where we vote for people to represent us in running the country. A true democracy would require the whole population to vote for every single decision that has to be made.
A media commentator made a comment recently that in the last 50 years, we have changed from a top down society, to a bottom up. What this means is that we used to admire, respect and want to be the same as the upper levels of society (not false people like celebrities) such as the engineers, scientists, managers etc. Now we seem to be admiring the bottom feeders such as the trailer trash "celebrities" (Paris Hilton comes to mind) and sports people (Fevola and Carey) and trying to be like them, with anyone who aspires to greatness in the sciences or business treated badly. This will lead to the downfall of our society, as no longer will people be willing to expand their abilities for fear of ridicule.
