Right - but part of the difficulty and expense in hiring teachers is that we've segmented it off as an expert population with high barriers to entry. If everyone who learned was also expected to teach, you scale the teaching population with the learner population. You can actually see the dynamics of this play out with flight training, since you get your CFI at ~300hrs total flight experience but nobody will hire you with less than ~1,000hrs, so you have this massive pool of certified teachers with 300 - 1,000hrs of experience available to teach as a consequence of the design of the system.
