The Mayans think we will survive till 2012.
I think they are wrong. What about you?
The classical Maya don't think very much at all, being as they're all gone. :p The modern ones don't make a big deal out of it. Snark aside, the end of the
b'ak'tun never, in Mayan mytholgy/theology/etc. heralded the end of the world or universe. Quite simply it was the end of the calender, in a similar fashion to the year 1999 ticking over to 2000. Humans being Humans, I expect that if the Mayans were still around plenty of them would doomsay regarding 2012 (Remember Y2K), but in reality it would be nothing more than the equivalent of our Millennial celebrations.
As to the thread topic in general I'm unconvinced that real world -isms can generally be applied to videogames. It just doesn't work that well for the most part, because giving the player realistic influence means a realistic level of power, which tends to mean not enough power to make the game fun. A 4X game might well have democratic government types, but you're not likely to get voted out, and even if you do (As can happen in Galciv 2) your party loses power and you lose their bonus, but you're still in control. As for economics, well, with a few exceptions you're running a
Command & Conquer Economy.
I'm convinced that more interesting things can be done (And have on occasion witnessed as much, e.g. Patrician III breaks slightly from this, and Vicky does to a greater degree) but there's a ways to go before we get to a successful, intuitive game in such a vein. Transport Tycoon is an interesting one, where you have absolute control over your transport network, but not terribly much say over anything else. The cities and industries build and develop based on how successfully you're providing the services they desire.
