It’s not like it ever had a chance. The only way democracy would have stood a chance, ever, was if people really knew what was good for them. That’s obviously not the case, since it entails a solid education, a degree of selfishness, and a lot of patience.
Take ten mature men (and/or women, if you prefer), of all intelligence levels, and from all walks of life. In short, amass ten ordinary folks. Now say one of them is absolutely brilliant, a genius. Two of them are very smart, hard-working, with a good grip on reality. Two others are just hard-working, physically strong individuals, decent folk that enjoy life for what it is. The other five of them dislike any kind of work, are rather dim and gullible, often vile and usually discontent, in constant need of guidance (that they normally ignore anyway).
