>The problem is that any hiring test that blacks and whites pass at different rates, is presumed racist. Never mind that the real issue might be that the blacks went to worse schools and received a worse education.

Your first sentence is the result of bigotry against those with "enhanced" melanin content, not the cause.

The cause is laid out in your second sentence.

Resolve the systemic bigotry (not just against those with enhanced melanin content, but against those with the least resources as, at least in the US, most schools are paid for by local property taxes, making the poorest areas the ones with the worst schools) and put us all on a level playing field and we'll be a much fairer society IMNSHO.
