Tough to quantify but I think most privilege or advantage is based on socio-economics rather than race, green being the main color that matters in this world. Just happens those two overlap rather significantly.
You get arrested and your parents can bail you out so you don't have to see the judge in an orange jumpsuit but instead are clean shaven and dressed up with them behind you in court. That makes a big difference.
You go for a job where your uncle is in the industry. You share similar interests and backgrounds as the people you are trying to persuade or measure up to.
If you kill your wife and her jumpoff in cold blood but can spend 10 million on the best lawyers in the world rather than get a public defender.
But if there is empirical evidence to the contrary I am open minded to read it.
