Class structures resembled pyramid, with the largest number at the bottom.
Explanation:
Based on the position of different people in a society, different classes are formed conventionally. The people holding the highest ranks are treated as the highest level of people and the class formed by them is considered to be the most superior. Usually, the people who hold the highest ranks are very less in number. On the other hand, the people who are subjects of these people who hold high ranks are large in number.
It is because of this aspect of society, the structure of classes placed one above the other having the lowest class at the bottom and the highest class at the top looks like a pyramid.
