If they sell you pay $5 for the drug and the next person in line pays $2k for the same drug, they are making $1k per patient. They are also writing off the $3k that they could be charging you as a charitable contribution, so they don’t have to pay taxes on the income. They hope that if they keep you alive, some day you will make enough money to pay full retail price.
I would say both New Orleans and Memphis should be in the East, since the US regions, as I learned them in school, would say both of those are in the Southeast while, for historical reasons, Minnesota is in the Midwest. Obviously, that would make the conferences unbalanced, so we could move Milwaukee or Chicago into the West.
