This is only real solution; even if individuals / businesses are making decisions based on good faith metrics (credit risk, criminal record, poor academic record) the protected classes will sue claiming it is because of race. Since there is no way to disprove, and even trying is so costly, it creates a "privileged class" who can get away with a lot because of the threat and reality of litigation. And of course, the scope of all laws creep over time always, so there is no way to prevent this with any measure of confidence. Which brings us to where we are now.
That was such a clear and concise analysis that even I void understand. Thanks fo posting.
