If Argentina were all German immigrants,

Controlled by Europe, Brazil is mixed-race and Argentina is white, for many reasons. First, there are few aborigines in Argentina and many aborigines in Brazil. Second, due to climate and environmental reasons, the agricultural development of the two countries is different. Argentina develops animal husbandry and Brazil develops planting, so the race varies with the change of labor industry.

With the Spanish invasion, South American aborigines, including Brazil, were massacred, but despite this disaster, many aborigines survived. There are not many aborigines in Argentina, and there are not many left after the Spanish massacre. At first, the proportion of nationalities in the two countries was different, but after the changes, it was very different.

Argentina has a warm and suitable climate and grasslands all over the country, which is most suitable for the development of animal husbandry. Like most European countries, animal husbandry is the most developed industry. Animal husbandry does not need much labor, so the demand for slaves is not so great. Brazil is different. Plantation industry is the only developed industry under the influence of Brazil's climate, but it is very labor-intensive, so European colonists introduced a large number of black slaves.

Different skin color cultures have been formed, so Brazil is nicknamed "the melting pot of races". Therefore, although the two countries are the same colonists, due to the different living environment and climate, managers need to formulate different policies for different regions in order to seek the best development, otherwise poor management will be replaced by other colonists. Changes in policies will naturally affect population development.
