I love Wilfred and Coleman, but think about this. How can a name be a marker for socio-economic status?There aren't rich names and poor names.

The names, in this case, are markers for ethnicity. Which people then assume are predictors of socio-economic status. That, I would argue is racist. The same effect was found for Chinese sounding names for example, even though Chinese immigrants are among the wealthiest groups in America.

It's also classist. What does socio-ecomonic status have to do with competence? A resume is filled with data points that are relevant to a candidate's ability to do a job. That isn't one of them.
