The two words I searched in Google images were “white collar job” and “blue collar job”. When searching ‘white collar job” the Google images were of mostly white men and women in suits. The suits are pretty normal considering the work environment related with white collar jobs. But a majority of the page is white.
When searching “blue collar job”, the entire page is construction workers. And the ethnicity is much more diverse.
This doesn’t necessarily mean that Google is being sexist or racist. Google’s “bots” are just regurgitating what we put up for them to find. So are we racist? Are we sexist? Or do we just live in a world that favors white men?
