Limitations: property is the distribution of power, so the privilege of nobles declines, while that of businessmen rises. Generally speaking, democracy is not fully developed, but the power between nobles and businessmen alternates!
Moreover, the implementation and reform of the democratic system in Athens have certain privileges for the nobility, so it has little impact on the aristocratic class, but there are problems in administration, because its Tao exile law and referendum are always held at citizen meetings, and inconsistent rulings often appear at citizen meetings.
Furthermore, because Athens is a direct democracy, the quality of citizens varies greatly, and its so-called democracy is not necessarily democratic, because it is decided by the citizens' assembly, so personal grievances will infiltrate into it, such as the death of Socrates.
