What is one reason (besides violence) that racism negatively affects our world?

Racism hugely effects economically. Theres a thing called gentrification and white flight. Gentrification example is Hawaii. Hawaii is a brown state, but because of white people moving there the natives are forced to leave their homes. White flight is when a neighborhood is white, but has an increasing number of minorities moving into the area, and because of that, and the people not wanting diversity the white people leave, thats why its called white flight.

You can look into it a lot more but that majorly effects the US, in places like New York, New Jersey, Detroit, Hawaii, California etc
