absolutely. the cartel doesn't help the top 2% of agents, because they're good enough to earn the 6% (or higher) anyway, but the monopoly works because the overwhelming majority of interested stakeholders benefit.
(that's not to imply that most agents are lazy though. a stat i dimly recall is that only about 10% of agents make enough to be full time.)
