There is no war against white males. 100 percent of our Prime Ministers have been white males (ignore Kim Campbell's 3 month reign). White males form 30 percent of the Canadian population. 

Similarly, 85 percent of CEOs are white males (I am throwing a figure - a wild guess). Similarly, 85 percent of janitors are from ethnic minorities, and many of them have Master's Degrees in Engineering.

As for excellence, if you go to an engineering class in Canada, it is dominated by Asians. However, as you go up the ranks of an engineering company, it gets whiter and whiter. Now either those Asians are incompetent (unlikely, because 40 percent of Silicon Valley startups are founded by Asians), or there is a subtle discrimination/ favouritism that takes place as they chose candidates for promotions.

The real answer is some blend of quotas and entrepreneurism.
