I think you don't understand how remarkably difficult it is to not only find a new drug/treatment, but also to then prove it's "safe" [enough] to market 20 years ago, the average cost of developing ONE new drug (counting failed attempts along the way, testing, certification, etc etc) was north of $1 billion US I guarantee it hasn't gotten cheaper in the meantime
