The search engine is an invention of white men from the imperial core that uses search data generated by a society dominated by white men which means it's machine learning is biased towards the perceptions of white men and thus all portrayals of "working class" are filtered through whatever a white dude would find most relevant.

Edit: as a white dude, I'm really one of the last people that should be asked about a fix for this, and I don't have one.
