Since you decided to make a racial accusation, why don't you find the proof instead of putting the burden on everyone else to prove your accusation wrong?
How can you 'prove' this? It literally has to be a thought experiment because the only way to prove it would be to apply for a job at the same company with the same crime as a non-white man. It's not an accusation it's a social thought experiment.
But if you're interested racial hiring bias has been thoroughly studied and well documented if you care to google it.
