Let's just think about this.
If the larger outfits have unions, how can they be hiring minorities below market value for wages? Isn't this something that the union protects against? From the department of Labor statistics:
Among full-time wage and salary workers, union members had median usual weekly earnings of $1,095 in 2019, while those who were not union members had median weekly earnings of $892.

I have seen numerous analyses that suggest that people in unions get paid better than people not in unions. This is just a fact, not an arguing point. The idea that he gets paid better without the union is a false economy. Also, seeing as unions can only contract out work to other unions, it looks like being in a union also helps with job security. I have to wonder if the people are purposefully leaving this non-union employer because they can get better employment with a union job. Not saying unions are the best thing in the world, just saying that this man's argument is nonsense.
