If Gilead charged $1500 in every country it wouldn't have been worth to invest in the first place.

Remember they paid $11B for the right to the drug and they still had to bring it through development.

Surely the right to the drug was only worth $11B in the first place because of $84k possibilities at the other end? If it was only ever going to be $1500, that $11B would have been adjusted accordingly.
