I believe you're right, it does seem to have had a significant effect. Perhaps it's also interesting to imagine the societal changes if law and policy prohibited discrimination based on being disadvantaged by class, wealth and income. We may well edge towards a genuinely more equitable society, rather one that just pays lip service to it based on one's identity. Though it's unlikely to ever happen, given the economic and political system we exist in. It would disadvantage the wealthy and well-connected too much for them to permit it.
