Just to be evenhanded here, I suspect that in most criminal cases the jurors are likely NOT in the same social class as the defendant. That said, having jurors be people you know seems a little unfair too. So a jury of perfect strangers seems greatly unfair in the postulated context of asymmetric privacy, and a jury of friends seems unfair as it's possible they would let you off regardless of evidence. Problem is, asymmetric privacy is a reality today. So, yeah, tough problem.
