“Ethnic” clothes and hairstyles are still stigmatized as unprofessional, “cultural” foods are treated as exotic past times, and the vernacular of people of color is ridiculed and demeaned. So there is an unequal exchange between Western culture – an all-consuming mishmash of over-simplified and sellable foreign influences with a dash each of Coke and Pepsi – and marginalized cultures. People of all cultures wear business suits and collared shirts to survive. But when one is of the dominant culture, adopting the clothing, food, or slang of other cultures has nothing to do with survival. So as free as people should be to wear whatever hair and clothing they enjoy, using someone else’s cultural symbols to satisfy a personal need for self-expression is an exercise in privilege.
