While a large population gives factories more employees, it causes the food supply to run low, therefore causing positive checks to be necessary in order to prevent the poor from overpopulating and blaming the government. In order for society to thrive, the population must be higher than the amount of food. However, population increases at an exponential rate, and food increases at a fixed rate. This means that eventually population will surpass food, and people will starve. To slow population growth, there are two kinds of checks. There are positive checks, which are natural disasters, and preventative checks, which rely on human judgement. When the poor blame the government and the aristocracy for their poverty, they do not realize that the true cause of their poverty is their fault. When a family’s income would only be able to support one or two children, the go ahead and have seven children. They then blame others for their own mistakes.
