1. According to the readings, the Constitution was written by the propertied class, including wealthy gentlemen, merchants, slaveholders, bankers, creditors, and land speculators. The excluded class included slaves, indentured servants, men who could not qualify for voting under property tests, women, Native Americans, and poor farmers. The difference between them is the propertied class owned land, slaves, capital and securities, while the excluded class almost has nothing and survived solely by their labor.
2. The early American class structure was different from the current one but had a similar fundamental structure. The difference is there was a clear legal distinction between classes in the early days, such as, property ownership, voting rights, slavery, and discrimination against women under common law. While everyone is legally equal today. The similarity is a small number of people owned production materials and wealth dominated politics while the majority have to sell their labor to survive.
3. The people who wrote the Constitution so afraid of democracy because they belonged to the propertied class. Democracy implies that a majority without property might use the government to redistribute wealth, abolish debts, and threaten the interests of their class. Therefore, they incorporated mechanisms such as the separation of powers and the electoral college to curb the power of the majority when they designed the constitution.
