Firstly, Laws favour those who know Law. Everyday, the poorly educated gets punished for not knowing Law. At the same time, those who are educated in the subject walks off getting richer with every mistakes that their opponents offend.
Secondly, Laws favour those who are rich. It doesn't matter much if one does not know about Law that much. He would have just missed opportunities to extract compensations on certain occasions. With an adviser or a legal consultant, he could at the very least prevent too much harm from being inflicted upon him.
Thirdly, Laws rely much on the judgment of a Man/Woman. Maybe sometimes a team of people i.e. the juries. Is there really fairness when personal prejudice and discrimination (however small the extent) come into the room which metes out legal punishments?
Having laws seemed to increase disparity between the elites and the non-elites. But we can't do without anyway.
