The answer is Commerce and taxing
The middles colonies had rich farmland and a moderate climate. This made it a more suitable place to grow grain and livestock than New England. Their environment was ideal for small to large farms. The coastal lowland and bays provided harbors, thus the middle colonies were able to provide trading opportunities where the three regions meet in market towns and cities. The Southern colonies had fertile farmlands which contributed to the rise of cash crops such as rice, tobacco, and indigo.
The New England colonies had very long and cold winter, making it hard for crops to be grown. The soil was pretty rocky and unfertile, so not too many plants were grown. Most farms in New England were small family farms. The middle colonies were called the breadbasket states, because of how much wheat and barley were grown. The southern colonies grew many things. The Southern Colonies were able to grow crops, fruits, and vegetables because of their fertile soil, and warm climate.
They must say that cash crops were grown in the middle colonies, that slaves were used on large plantations in the south, and that there was subsistence farming in New England.
The Declaration of Independence states that when the govt abuses its power, the people have a right to change the government or even overthrow it.
