Is it a matter of race or discrimination?

Is it a matter of race or wealth? I don’t want to lean on either or. I believe it’s a matter of ethnicity, as well as wealth. When is it a matter of wealth? I’d like to think that we see this discrimination more often in countries that don’t have a diverse amount of ethnicity. For example, in Mexico you can’t express hatred towards someone in terms of their ethnicity. Instead, you’ll see this segregation or division in wealth classes. The rich will socialize with the rich and the poor with the poor. If you’re seen with the “chusma” (peasant, commoner) it can damage your “reputation”. When it comes to ethnic discrimination, wealth does not matter. A lot of celebrities are constantly oppressed, discriminated and abused because of their ethnic background. Some examples would be: Michael Jackson, Little Walter, Billie Holiday and many other Jazz musicians, etc. They could have billions of dollars and still be discriminated; of course those were different times, but you’ll still see acts of racism nowadays – not as drastic as they used to be, nonetheless they still occur. Nowadays, racism is disguised with sophisticated language and mild acts of hatred.
