We consulted with the writers of The Pitt on this storyline. The scripts don’t always get all the insurance and health policy details right, but I can vouch for the fact that they definitely work hard to understand the nuances. It has to work as a compelling story, too.

Pet peeve: un-self-aware academic junket culture. We spend $2000 to attend conferences where 75% of speakers rail against American inequality, while we splurge on $75 dinners, stay in $300/night hotel rooms, and take a $50 uber ride to avoid a 3-stop subway ride that would cost $2.50.
