I own a business. I found it 40 years ago. During that 40 years I have 
employed Chinese and Vietnamese boat people, a Russian immigrant,
males and females and — I am not sure of the required terminology these days — people of colour ... Is that correct?  And I do business with 
people who immigrated to Canada whom are as diversified as 
it seems would be approved by university administrators. 

I do business with French speaking entrepreneurs and while neither they or I speak the others language with anything like proficiency, we manage to do business and presumably make money. 

I am not forced to employ those I do employ or do business — or punished for not employing or not doing business.

But I do not do business with the inept hire the inept ... simple as that.

Why would I sabotage my interests, my employees interests, or my
customers interests by employing the inept, the troubled, or confused?

Capability comes in a rainbow of colours, ethnic groups, religions, and
etc.
