"A superfluity of wealth, and a train of domestic slaves, naturally banish a sense of general liberty, and nourish the seeds of that kind of independence that usually terminates in aristocracy"

This quote by Mercy Otis Warren speaks to the risks of having excessive wealth and too many domestic slaves. When individuals have a lot of money and a lot of servants, they can become disconnected from the truth of the world and the struggles of the general population. This disconnect can cause a sense of superiority and privilege, which can lead to a desire for self-reliance from the rest of society. This kind of self-reliance can cause the development of an upper class, where a small group of people have all the power and wealth, while the remainder of the population is left with absolutely nothing. Warren's quote is a warning against the threats of having too much wealth and a lot of servants, as it can result in the development of an upper class that can be hard to break down.
