The fact that its considered to be morally wrong to "discriminate" who you hire is so strange to me especially for private/smaller enterprise companies. Its your company and it should be your right to create the working environment to your liking, may it be on merit or compatibility. If it fails you got no one to blame but yourself and if it succeed then you have a working formula. Being force to pay someone to "work" on the basis of their race or sex is bizzare.
