Seriously, though. A citatel of very intelligent and powerful individuals who banded together for mutual protection and... needlessly reproduced our society's structure and made lots of them work menial jobs or jobs unrelated to their talents and interests? Let us say they need police Ricks, why do they need salesmen Ricks? Even factory working Ricks seem too much.
One point I'd like to argue is that not all these Ricks are as smart as C137 or Rick Prime. These two invented portal travel on their own, which means they are in a whole different league from that fact alone. Most of the other Ricks you see got the hand me down teleportation. I would agree there should be a few smart ricks that should easily be able to put systems in place to solve this labor issue, but remember, our Rick c137 built this place to find Prime, to which he wanted as many ricks at this location as possible, which could mean making more meaningless jobs to fit more ricks in.
