The answer to this question can be quite subjective. Some people will say that the telephone is the most important invention, or the automobile, or the plane, but for me personally, I'd choose antibiotics.
It is a modern-day invention (as opposed to the Middle Ages, for example) which changed our lives for the better. Before penicillin was discovered in the 1920s by Alexander Fleming, people were constantly dying because of most harmless diseases. But after antibiotics were invented, people were given a chance to recover from their illnesses much more easily.
Answer:
The richest people in the society (like elon musk or the kardashians lol) were called "aristocrats". Over a third of society were women and children, the others were men. Women were considered citizens but were not able to vote. Freeman, men who were not slaves (but were second-class to the common people), were not allowed to vote or participate in government (like run for senate or smt). Freemen made up around 10% of the population. They often were not born in Athens and moved there to find good jobs and make money. Freemen were often craftsmen and merchants. When the economy started going up, the number of merchants increased and trade increased as well. Slaves made up 1/3 of the population, and slaves were mostly prisoners of war (people captured in war). Slaves were considered private property, owned by an individual and not the government.
