If you don't encounter the justice system then almost nothing on your list is relevant. Most black kids won't be directly affected yet they do much worse at school. What specific examples of systemic racism have been shown to cause that? I've read some of the research and it's inconclusive. Many possible causes are suggested, a big one being cultural factors of the mothers.

So a normal black kid can safely pursue life without worrying that he or she has been held back by systemic racism.
