What are the similarities between ancient Rome’s and Ancient Greece upper classes

Both Greece and Rome are Mediterranean countries, similar enough latitudinally for both to grow wine and olives. However, their terrains were quite different. The ancient Greek city-states were separated from each other by hilly countryside and all were near the water. Rome was inland, on one side of the Tiber River, but the Italic tribes (in the boot-shaped peninsula that is now Italy) did not have the natural hilly borders to keep them out of Rome.
