Promotes a way of thinking that leads to what?

Sorry dude, I'm afraid that's thought police shit. And again, if his numbers are wrong, (and I suspect they may be) then you can't believably call him out on them without stumping up with alternative numbers, duly referenced etc.
They're baby doc's, residents, apprentices, a sort of hangover from when they really did live on site. The cost to train them to that point is massively subsidised, and if that subsidy were included in their remuneration then yes, they're already hugely overpaid compared to overseas models.
Same with any tertiary training, if you're paying for it yourself then you're the only one that should benefit from the eventual revenue the training allows. If, as is the case with many professions the training is substantially subsidised then the taxpayer has every right to expect that training to benefit the community as well.
In which case the fact that female vets are less productive is certainly relevant to any discussion on that funding.
