Australia is known as the country with the most serious racial discrimination. What is the social root of this phenomenon?

Speaking of racial discrimination in Australia, I used to see many news on the Internet that Australian residents verbally or physically insulted Chinese in China. It is true that racial discrimination in Australia is very serious. The root of this social root comes from racial discrimination left over from the colonial era.

As we all know, after Columbus discovered the new continent, these continental plates began to connect and the world gradually became a whole. With the rise of the first and second industrial revolutions, the capitalist countries in western Europe developed first. After they developed, the first thing they did was to develop colonies and seize more resources. Therefore, it was during this period that white people began to sell slaves, and many blacks and yellow people were transported to work for them all over the world. We know that Australia is an immigrant country and there were not many aborigines in the past. The main population is black and yellow slaves who were trafficked in the past, and some white people who were dominant at that time. These white people are used to bossing around blacks and yellow people, and even their descendants will be influenced by their ideas. Racial discrimination against blacks and yellow people has been deeply rooted in their hearts. After the end of World War II, although various countries began to continue to develop, the countries represented by the yellow race and the black race were far less than the capitalist countries where whites lived at the beginning. It is precisely because of this obvious economic gap that many whites look down on blacks and yellow people. Even if developing countries catch up gradually, racism carved in their bones still makes them look down on blacks and yellow people.
