To be clear, I don't believe that "racism" is at the heart of most of the problems we are facing today, and I don't believe that eradicating racism (if that were even possible) will solve them. Most of them boil down to a lack of accountability, and that boils down to the monopoly state. With that said, if you don't think that there are structural and institutional barriers keeping some minority groups (and especially low-income minority groups) at a distance from opportunity and success, then you need to look a little more closely.
This is just one, very small, example: It's a documentary I made a few years ago, detailing how the Howard County School System - one of the top-rated public school systems in the country - enforced a policy denying choice (in the form of being able to change schools within the system) to parents. The doc also demonstrates how this policy of selectively denying access to the better schools was more stringently applied to minority families.

Oh and yes, the Howard County Public School System refused to speak to us for this project.
