Yes, that is correct. 88% could not vote, but I'm assuming you did not look at the numbers too closely. The Athenians added slaves and metics (free foreigners) to their population number. The reason that only 12% can vote is because of their 240,235 people, 80,000 were slaves, 25,775 were metics, and 74,750 were children. All of these people clearly can not vote, for it will not be for the benefit of the country.
Those numbers are true and you have assumed that im trying to argue that the government was corrupt. It wasnt. Im simply stating that fact that the law making system in ancient Athens could in no way be catagorized as a democracy. Democracy is based on equality and freedom and the chance for the citizens of a population to govern themselves. As you stated, of 240,235 people, 80,000 were slaves, 25,775 were metics, and 74,750 were children. Those people are in no way part of a democracy.
A democracy has three branches of government. In ours, we have the executive, legislative, and judicial. In Athens, the had: the Assembly- the voters, the Council of 500- those who make the laws, and the Judges- those who make a fair case with a jury on crime and legal issues. This sounds much like ours. The metics and children were free, so I'm going to go ahead and dismiss that they are not free. America had slaves for over 100 years after our independence. Simply because a nation has slaves does not immediately make it not a democracy. In a democracy, people vote (the Assembly) there is equal justice for all (the judges), and laws are made for the benefit of the people (the Council of 500).
The council of 500? Do you even read your arguments before you send them? Even in the most direct democratic area of Athenian government (the assembly), there is still only limited personel that can vote! You must be a citizen male over 20 with military expirience! Maybe you should look up direct democracy because thats not it! And the Council of 500? Do you know what a Parlimentary system is? lets just say its not equal justice for all!
