Very few people study Ancient Greece these days.
For one thing, the Greeks were terrible misogynists. They seemed always to be at war. Their politicians were mostly driven by personal ambition, and many of them were plainly corrupt.
The richest of the Greek city-states, Athens, founded its wealth on slave labour and the economic exploitation of its smaller and weaker neighbours.
And yet, out of all that mess came great art, mathematics, literature, philosophy, and even science and medicine.
The Greeks were, in short, nothing at all like us.
Addendum: Greek words that are completely irrelevant today:
Misogyny, democracy, oligarchy, plutocracy, autocracy, demagogue, sophistry . . . well, you get the idea.
