Interestingly China seems way ahead, peasants still easily outnumber the rest but luckily it is not a democracy.
Why do you think that?

Do you mean why do I think that it's not a democracy or why do I think that it's lucky it's not a democracy?
The former is probably not very contentious. However the West are always very quick to denounce countries as not democracies (with the strange recent exception of Iran) and ignore the fact that almost every country has some form of representation and elected councils (eg Libya did, Cuba does). So you could argue there is some democracy in that the Party positions are elected within the Party, but most would agree China is not very democratic.
By the latter I mean the World and China itself are lucky not having a perfect democracy at the moment because, being early on its capitalist period, the vast majority of Chinese work on the land. If it had a perfect democracy (i.e. the country run in the interests of the majority) China would be being run in the interest of the peasants. Consequently it would probably be occupied by some other country.
They tried that with collectivisation and it lead to mass starvation. After the cultural revolution, which was meant to reinvent the communist country, but just made it worse, their choices were to go the route they have gone or become a bigger version of North Korea.
One party states do have elections, but the real power is held in a rigid autocratic way, where elected assemblies rubber stamp, what has been decided, with at best a few rough edges rounded off. This is like the old USSR and the current EU. In both case the elected assembly could not introduce legislation. Under the Soviet system this was the Politburo and with the EU, the 27 commissioners plus the commission president.
What will happen in China is interesting where the Government controlled industries and Banks are very corrupt and making big losses and with the way the Chinese Libor rate is rising at the moment, suggests their economy could be in for a hard landing over the next few months.
The reason that autocratic countries are generally poorer than democratic ones where you have checks and balances is that in more democratic free market economies capital is allocated much more efficiently and productively.
