There are two ways of doing a business.First, you can be biased (say racist) & choose less competitive people & make losses. Second is, keep your personal preferences to yourself (probably more suitable for choosing your GF or BF), be shrewd & impersonal, choose people with highest abilities. Usually, the second way is more popular world over for obvious reasons. Racism at work place is promoted by those employees who are substandard & want a cover up by forming a particular lobby. But then again the owner of the company will soon learn the hard way to get rid of such people.
