In most cases this will be easily solved by on-the-job training, but with doctors there is also the added problem of a bureaucracy that has acted deliberately to restrict the supply of doctors, so as to protect the wages and prestige of that profession. That’s not to say that these problems don’t exist, but describing them as labor shortages that can be solved simply by importing more bodies is misleading.

all that those hoops means is that the lag to fill them is a year or two. which sounds like a long time but there's always another graduating class coming along, if the employers are willing to pay competitive wages.

And that's a big fucking goddamn IF.
