I would argue the vaccine for Covid is essentially a cure. And the economics aren't that good. People got it once. They may or may not take a booster every couple years. And that is for a disease that everyone was impacted from. Meanwhile, a drug like viagra can be consumed several times a week for decades. I don't think its pharma execs are sitting their blocking cures, but it is true that they will looks at risk/reward when deciding. If most drugs only have a very small chance of being approved (lets say 2%) and costs billions of dollars to move through the process - of course those that are needed over and over are going to be funded through research more.
