In a capitalist system, there's a principle that if you invest, especially in a long-term risky investment, if something comes out of it, you're supposed to get the profit.

Now take a look at the way the Drug War is conducted over the past 40 years. It goes back farther, but start from 40 years ago: There's very little spent on prevention and treatment. There's a lot on policing, a ton of stuff on border control and a lot on out-of-country operations.
