Even if researchers themselves are motivated by only the noblest of goals, their need for funding forces them to take into account profitability. That is why we have so-called “orphan drugs,” from which not enough money can be made because they cure rare diseases or diseases (like malaria) that affect people who cannot afford to pay for them.
即使研究者本身的唯一动机是目标的高尚性，他们也需要筹资，因此不得不算计利润。这就是为什么会有“孤儿药”（orphan drug）的出现。孤儿药因为只能用于医治罕见病或患者通常无力支付药费的病症（如疟疾）而不可能赚到足够的钱。
