It's not surprising to know racism is really strong in Latin American countries, in fact, this societies have an unwritten laws based on skin color rather than merits in much cases, light skin color is a key to climb the social ladder in those countries, appearances are one of the most important aspects to get good opportunities, for example, in Colombia surgeries are popular among women to get a more Caucasian appearance, but some of the most interesting social phenomenons is located in the big country of Brazil.
According to the Washington Street journal, Well-off women tend to select U.S. sperm donors whose profiles suggest they will yield children with light skin and blue eyes, which would make their kids more successful and get better education and opportunity jobs in the future, the demand for American sperm is skyrocketing in that country, allowing new industries to take shape.
This societies have been working like that since their creation as Nations, one of the reasons why these countries are not categorized as one of the most racist is only because there's not a single law that institute discrimination or racism, that, according to some investigators is interpreted as if racism doesn't really exist in Brazil.
