Explain the role of u. s. investors in latiin american economies and the role of the oligarchy in argentina and brazil.

The US investors in Latin America were really investing in themselves and their mother country's economy, not so much in the Latin American countries. They exploited the natural resources, exploited the labor force, and were taking the profit out of those countries and into their mother country.

In the two largest countries of Latin America, the local oligarchy was controlling the things. It was only a handful of people in both Argentina and Brazil that were controlling pretty much everything in their countries, especially the economies. Eventually that led to big revolts as the ordinary people were put in terrible situation while few individuals were enjoying most of the wealth of these countries.
