Aspirin is dirt cheap in the United States (~$2.50 / 100 pills) and has been for decades. Why?

I’m not being paranoid, but it seems like big pharma has colluded to keep the prices of most medicines we use extremely high. I am not talking about stuff like Tylenol, or other branded things. <br><br>Aspirin is a great example. It’s 2.50 / 100 pills in the US. Why? It’s not like there is competition, drug companies have a monopoly on aspirin, it can’t be made at home. But yet it’s dirt cheap.<br><br>It’s honestly even dirt cheap in other countries. <br><br>I can see how it would be expensive in developing countries, but why would it even be cheap in countries like Switzerland? <br><br>Why did drug companies collude to keep the prices of this one drug low?
