I'm glad you asked. Racial discrimination when hiring is a problem and can be observed easily.

For example this meta study, that looked at many experimental studies in 6 different western counties, shows how racial discrimination is a problem when hiring. This has been demonstrated in experimental research by sending two resumes to different workplaces. They show the same level of qualification, but one of them is from a white on one from a person that is not. You do this a lot, like 200 times with 200 employers and see how often both candidates are invited.

And consistently you can see that white people are invites, while racial divergent people are not.

From the meta study this reads like this:

Persistent discrimination in labor markets in North America and Europe has been demonstrated most clearly by field experiments in which investigators use testers or submit applications by mail or over the internet for jobs with clues indicating the race or ethnicity of applicants (5–7). These experiments show that on average in Western countries native Whites receive about 50% more callbacks than similarly qualified non-White applicants (5).*  This does not include significant additional discrimination that occurs after the callback (8).

*wave hands*

As a white middle aged man my privilege is everywhere. The problem is the people that don't see it everywhere. The world is run by my peers to this day and yet you have some of my spineless peers screaming bloody murder because black people should be offered the same odds getting a job if they're qualified.
