You don't need postscarcity to do that. I was born in communist Czechoslovakia (my father was an academic). Government allocated jobs for academics and researchers, and they pretty much had tenure. So you could coast by being unproductive, or get by using your connections to the party members (the real currency in CSSR).

After 1989, most academics complained the system is not merit-based and practical (applied) enough. So we changed it to grants and publications metrics (modeled after the West). For a while, it worked.. until people found too much overbearing bureaucracy and some learned how to game the system again.

I would say, both systems have failure modes of a similar magnitude, although the first one is probably less hoops and less stress on each individual. (During communism, academia - if you could get there, especially technical sciences - was an oasis of freedom.)
