Systemic racism (mostly known as institutional racism) is a form of racism expressed in the practice of social and political institutions. It is reflected in disparities regarding wealth, income, criminal justice, employment, housing, health care, political power and education, among other factors.
It is when whatever you are doing lasts half the time that it would normally take.
I would have to say during the industrial revolution. Many new inventions were being made and America started taxing goods being shipped to other countries. To remove taxes from certain countries, they moved factories to other countries so avoid Tariffs. It wasn't the colonization of America because America wasn't a country yet. It wasn't the reconstruction or world war 2 because the factories were already there from the industrial revolution.
Hope I helped!
