In the late 1800s, people in many parts of the world decided to leave their homes and immigrate to the United States. Fleeing crop failure, land and job shortages, rising taxes, and famine, many came to the U. S. because it was perceived as the land of economic opportunity.
Based on my knowledge, the scramble for Africa was largely because the industrial revolution was springing up all over the world in largely European countries and they were at a point where resources were running out. Gold and other valuable metals were discovered in Africa as well as timber. The surplus of resources in Africa made it very valuable to these industrial countries so they all made a huge "scramble" to Africa. Also, the idea of merchantilism, the idea that the amount of land a country owned defined its wealth, was still very popular so these countries wanted to make a huge land grab.
