I have had the same suspicion.  If I'm not mistaken his company was fined by the government for discriminatory practices really early on in his career.  I suspect it taught him to stay on the right side of the law.  He is sharky so I'm sure he comes close to the law at times but given how everyone has crawled up his ass looking for something to use to get rid of him and come up empty handed I can only infer from that there is no dirt to be found.
