The Daily Economy is a free-market economics site publishing articles on policy, healthcare, debt, taxes, and regulation.
HN commenters cite it for the argument that a cap on federally funded residencies creates the doctor shortage, and for an article on century bonds.
I'm close to B. In the 80's they tested how appearance affects people. Some women were given a facial scar and went to interviews while others were left as is. The scar group reported higher levels of discrimination than those without the scar. Tricky thing was none of them had scars in the interviews. The women that thought they had the fake scars had a "touch up" and the testers removed it.

Worth noting in this context that the scarcity of doctors is artificial, due to a low cap on the number of federally funded residencies. We could also let more doctors immigrate. My understanding is we make immigrant doctors go through a lot of hoops to validate their foreign training.

In the USA/Canada number of doctors minted is caped by the cartel of doctors. That costs non-trivial money and lives lost.

The linked article on the idea of forcibly converting short-term bonds to century-long maturity periods is well worth reading: https://thedailyeconomy.org/article/turning-treasury-securities-into-century-bonds-is-a-dead-end/
