So the reason there are deficits in poverty and education are...poverty and education?
Here's another explanation: most indigenous people live in the middle of nowhere, away from colleges, universities, and good schools and where the better educators live & teach, not to mention away from most industry and good jobs. Not much different than rural or small town whites who live in the middle of nowhere and are uneducated and poor.
Blacks in Canada typically come from among the poorest and least educated countries in the world. Black families also have a high single-parent rate and high rate of children out of wedlock and a high rate of teen pregnancy etc, essentially dooming the families to poverty and creating education gaps for their kids because they can't get the same homework help of kids in 2-parent families.
We shouldn't be surprised these groups have among the worst income, education, and crime outcomes? Any data ever gleamed on crime is going to lead to the same risk factors.
There are factors like racial profiling and over-policing in the justice system that make these issues worse, but the fact that black and indigenous people commit higher than average rates of crime also feeds into these biases, and it becomes a feedback loop reinforcing each other. We can and should try to lessen these profiling issues, but even cops and judges who were AI robots and perfectly fair will not solve the poverty/education gaps.
