The problem with the old boys's club is that it's essentially networking. In other words Japan Finland and China all would have this and is has little to do with bias. It's basically networking.

Yes there are exclusionary clubs which bar specific classes of minorities but on the whole they don't work that way. It's like saying frats are biased. Yes they are and the world would be better off without frats and their counterparts elsewhere, but I don't think they are mainly perpetuating racial discrimination. Rather they work as a job network and business network for their members.

I could be wrong. If so illustrate.
