Let’s not try to make capitalism as a purely meritocraic process. Family and other connections help even Yale graduates get a leg up on the competition. Thomas doesn’t mention this, but his lack of any such connection probably hurt him as much as the downplaying of his degree. He was fortunate in that Danforth was taken with him. IAC, Richard Nixon had a similar experience. When he graduated from Duke Law School , no New York firm offered him a job despite his excellent record. Too bad: he would have made an excellent corporate lawyer. His background was almost as deprived as Thomas’.
I don't see any way to make it so, people being what they are, and I'm not sure that I would even want to in my vision of a perfect world.
That being said, I think that our system of laws is something that we have more control over than some other things in this universe, and when an obvious injustice is identified I think that it's beneficial to analyze it, learn from it and work toward correcting it.
