What are the advantages of having a civil service system to select government workers?

I believe the answer is: that it eliminates the aspect of it being hereditary.

Because of this system, you won't automatically get the job simply because of your relation to the previous worker (practice of nepotism).

With this system, the government could obtain the more competent workers which is much more likely to produce greater work results.

answer: ‘no one should be discriminated against because he or she is not from a minority group’

because—> affirmative action means ‘a policy or program that provides opportunities for traditionally disadvantaged groups to them overcome the effects of discrimination’
