"If it is true that maintaining a thriving middle class is the objective of nation states, and yet we have not been able to sustain as proportionately large a middle class as the Ancient Greeks were able to more than 2000 years ago, how can we say our civilizations have made any real progress at all since 300 BC?"
You have limited data available for comparison.
And dishonesty upsets me and offends me, so I'm going to be blunt about this next point:
Even accepting whatever numbers you've chosen, your claim that we have a smaller middle class, by proportion, is either dishonest or stupid.
The numbers referenced in that paper are only for citizens--a minority of the population. And a privileged one at that, disproportionately wealthier than slaves/women/aliens. Nowhere can you conclude that a great % of Greeks were in a "middle class" than modern states today. You're either lying, hoping to be perceived by idiots as making a "point," or you don't understand that the paper you've linked in absolutely no way provides a basis for claiming ancient Greeks of any city-state had a higher portion of their population in the middle class than any modern nation.
This is not a matter of opinion. You either don't understand the simple numbers referenced or you're lying.
Your comments on slaves are, again, either offensively ignorant or outright lies. You've already demonstrated that you have absolutely zero knowledge of ancient Greece. In your opening post you didn't specify a city-state or time period. Here, again, you make a massive generalization which is absolutely false. This is just offensive. You know you have absolutely no idea what you're talking about, yet you continue to just make things up and post them anyway.
"I think this is rather shocking, isn't it? "
What's shocking is that you don't understand the numbers you're referencing, you don't understand this, and you continue to embarrass yourself anyway.

xeno posted "BULLSHIT" and it was not edited. As this is a word I would like to use a lot in reference to dishonest and ignorant posters, I shall take note and this word will surely appear frequently in my posts.

"If all the BULLSHIT we have gone through as a civilization over the last hundred years WASN'T about establishing a strong middle class, then, what was it all for? Was it for making a few rich, and keeping the vast majority at subsistence levels?"
It was about freedom and people being rewarded for their productivity. We've achieved this and have a proportionally much larger middle class than any city-state in ancient Greece ever had.
"I thought the whole point of civilization was the middle class."
It's not.
"Again, why is it that in this regard, we can't seem to do much better than the Ancient Greeks in spite of all our technologies, wars, constitutions, laws, etc., blah, blah, blah?
Why can't we have a as big (proportionately) a middle class as the Ancient Greeks?"
Ours is bigger. The question is what was so faulty in your education. The paper you referenced refers to "citizens" about a thousand times. It'd be hard to read and not understand that none of its numbers applied to women, slaves, nor aliens.
Additionally, your claims about slavery are absolutely laughable. While, just like anywhere else, not all slaves lived in as horrible of conditions, your comparisons are just ridiculous. This is just trolling, because you could find 100 sources to back me up and 0 to support your claims in an hour.
" That their "slaves" were probably wealthier relative to the wealth distribution of their society than most of are today relative to the wealth distribution of our societies, is a very sad state, for, if anything, the middle class of our day and age should be far larger a proportion to any society, especially one that had slaves.
I mean, their SLAVES were apparently better off than most of us today."
hahahhahahaha! hahhahahahahhhahahahahhaa! Oh my god this is retarded. Nobody is prohibited from voting today because they're poor or on welfare. 0 slaves could vote or take part in politics. Most people on welfare today have cable tv, cell phones, and air conditioning. Slaves had... hahahhahahahahahhahaahha!
You can't be serious. This is possibly the dumbest bullshit I have ever read in my entire life. It's not like you're talking about a minority opinion held by some scholars/archaeologists/historians. You're just making up some of the dumbest drivel I've ever seen. You're repeatedly lying about numbers used in the paper you referenced--This isn't a matter of opinion: The paper does not back up any of your claims, it dismisses them.
