Why does the government need to spend money on slots at all? Do other countries do it like that?

Because it makes pretty much no economic sense for anyone else to do it

One of many failure modes of the glorious and totally perfect Free Market

Yes most other countries use public money to educate their doctors

I think other funding models simply haven't been explored. I'll pull one out of my ass. The hospital does it themselves. In exchange the doctor works at the hospital for the next N years, or pays a contract break penalty. The hospital can pay the doctor somewhat less than market rate and doesn't have to deal with staff turnover.

It should be obvious that other funding models will be invented if government funding goes away. Because the alternative is no new doctors and people start dying without treatment.

Residency training costs like $750,000 to $1.5MM per physician

Primary care doctors would have to work 12-15 years while giving up 25% of their gross salary just to pay for the residency program. They'd also have to pay x% of their salary to pay for their debt from med school training before the residency.

People just wouldn't go into the field, which is already happening even in a world where the residency is funded. The economics of being a doctor are simply not that great anymore, especially relative to other things you could do.

There is an infinite number of jobs that would be great to have but we can't reasonably fund and so don't exist.

We currently live in a timeline where there are no new personal one-to-one tutors for middle schoolers and therefore every single middle schooler in the country receives subpar education, causing vast amounts of economics losses as compared to if they could be trained more thoroughly.

But that's just the way it is!

And how much do residents generate in billings?

Your numbers may also be off by a lot. It'd be great to see some sources. https://news.ycombinator.com/item?id=45507076
