If Spain had colonized North America and Britain had colonized North and South America, what would be the current international economic development and what would be the order?

First of all, history has no assumptions. If it is true: 1. There are many indigenous people in South America, unlike North America, which has fewer Indian tribes. This means that Britain can only colonize South America because there are many mountainous plateaus, Amazon tropical virgin forests and few plains, so the British When there will be very few immigrants, it will only be possible to adopt colonial methods like the Western powers. 2. There are few people in North America. The Spaniards could only transport Africans to develop gold mines and other resources, and they would also immigrate, but they would not adopt the British constitutional monarchy, etc., and develop into the later presidential system. Spain is a feudal king system, so its institutional influence on the future of the United States will be reduced. However, due to its vast territory and the influence of immigrants from other Western countries, it will also develop into a good country.

The ranking will be: the United States and China are equally matched, but the United States is first, China, Japan, Germany, etc.
