In a purely meritocratic system, the result is the same as well due to the effects of crowding. If you have 100 applicants for a position, 90 of them from one background and 10 of them from another, the odds are that under a pure meritocratic position that all of your hires will end up being of one specific background. Which results in a downstream effect of other perfectly good candidates being filtered into lower quality institutions due to no reason of their own.
