Consider how things work if nobody games the system. Each contractor is really being operated by the claimed owner/CEO/president. If the best contractors for a government agency's needs all happen to be run by white males but other less-good contractors exist, some of those better choices need to be rejected. The people running them are hurt by not getting the contracts. The government agency is also hurt by not getting to use the best contractors, and of course this hurts the general public due to government waste.
