Understanding the sociology of the systematic racism
There are many factors that cause systematic racism. Systematic racism is a social trend/movement in many levels of a society (from the government, public sectors like health system, banking, educational system to personal lives like churches, families, friends, etc). The Nazi Germany is a good example of the systematic racism in which the government, public and private sectors, and most individuals had a racist ideology that caused the death of millions with the financial cost of the second world war.
Which social factors caused systematic racism? Are these factors personal or governmental?
What accelerated those factors? Do those factors have correlation? and how can a society control those factors?
The list of factors can be at the macro level (like the government, educational system, financial system, health and welfare systems) as well as the micro level (individuals impacted by their psychological concerns, or impacted by families, friends, their level of education, their financial status, etc).
