Almost half of the new "immigrants" who came into the United States in the late 1800s

eventually returned to their home countries.

Explanation:

At that, the immigrants came because they heard the rumor that American gave out several pieces of free land that they can turn into any business they want through the Homestead Act.

But the influx of immigrants that came in surpass the amount of land that is available to be given away. As a result, many of these immigrants did not get the land and find difficulties in finding a way to fulfill their basic needs. So, almost half of immigrants in late 1800s decided to move back to their hometown.

social contract theory basically says that all individuals are born equal, and provided a god given right to consent to be governed. american government is based of this

thomas hobbes and john locke said that we are selfish, individualistic, and constantly at war with each other, therefore we need to be controlled. 

government is defined as the legitimate use of force to control human behavior within territorial boundaries, here comes in hobbes and locke.

hobbes takes the part about controlling human behavior. while locke takes the part of legitimate use of force, since force is not legitimate unless there is consent of the people. 

there are basically 3 goals of the government: 1) maintain order by protecting life and property. 2) providing public goods, those which are typically not provided by the public sector, such as roads and education. 3) promote equality be it political, opportunist or outcome equality.
