There is much more elasticity than you think. Most medicine is not about “not dying”. Here is an example: I get heartburns pretty often. I take a heartburn medicine omeprazole daily. It’s an over the counter drug, costing something like $0.3/dose. If they bumped the price to $16,000 I would just stop taking it, and started getting regular heartburns again. These suck, but I lived with them before finding this drug, and wouldn’t pay tens of thousands of dollar annually to get rid of them.
