1. The Constitution was written by the upper class, which included wealthy landowners and property holders. They had the power and resources to influence the government. The excluded class included the disenfranchised, like slaves, indentured servants, men without property, and women. For example, these disenfranchised groups did not have the right to vote or a say in the meetings where the Constitution was created.

2. The social class structure of early United States society was different from ours today. Back then, there were clear divisions between the wealthy and the poor, and many people were excluded from having rights, like voting. Today, while social classes still exist, there are more opportunities for people to participate in politics and society, regardless of their wealth.

3. The writers of the Constitution were afraid of democracy because they worried that the lower classes might gain too much power. They thought that if everyone could vote, the needs of wealthy landowners could be ignored, leading to chaos. They wanted to protect their interests and ensure that those with property had more influence in government decisions.
