Which factor drew many immigrants to the united states and allowed people to prosper by relying on their own resources and beliefs?

One factor that drew many immigrants to the U.S. and allowed people to prosper by relying on their own resources was the type of government the U.S. has. In a democratic society the people are free to choose their career. Many immigrants also came because America was considered to be the "promised land".
