What I noticed is that to not lose money, they need lots of brief visits. Do the checkup, come in later to review the test results, then schedule a follow-up to decide on a referral (or not). Everything after the first visit could have been done with a (voice-only) phone call.
Maybe video visits were supposed to make it easier to generate billing with less driving, but it didn't work out that way.
Ultimately I went with an HMO, where the doctors can provide the same minimal amount of care but not jump through hoops to do it.
2) When they do have other people for it (which yes, is very often to your point), they're paying those people
3) When you pay other people, you need to make more money to pay them with
4) To make more money, you need more volume
5) To get more volume, you need to spend less time with each patient
You've changed nothing about the core dynamic of the system, just interjected with a meaningless and not-even-totally-true detail.
