Addiction is the antithesis of "capitalism."
Capitalism presupposes choices in the face of alternatives to satiate a need or want. Addiction is need never satiated. Addiction promises happiness, but delivers misery. It's a mad doctor administering disease while promising a cure.... Crony Capitalism is rather similar.
To create demand is not to create addiction. Demand is a rational longing, it can be filled. Addiction is irrational craving; it can never be filled. Doughnuts will eventually satisfy your hunger and end it; heroine never will....
Demand convinces customers to come back of their own free will and rational choice. Addiction forces victims to return, forever seeking but never finding relief, that will not come.
This is not to say demand is entirely voluntary, but it is fairly honest, if one is honest with one's self. Calamity is part of life, and the key is legitimately offering a possible solution. The car mechanic fixes your automobile's crash, the plumber unclogs your pipes, and the doctor diagnoses you with the actual intention of treatment if possible. The heroin dealer gives you the first hit free, knowing all the others will more than pay for it, that there will be many others, and that hurt, not help, is what he is really selling. That is, the drug dealer does not solve problems, he creates and compounds them....
I have seen mothers literally sell their children for crack. I have seen once happy couples fall to pieces over meth. I have seen the most promising futures impaled on a heroin needle. I have seen life savings gambled away. Through many a twisted and misguided philosophies, humanity seeks respite from woe and rest in happiness. It looks in all the wrong places. Be it chemical, psychological, or more often a mixture of the two in most cases, addiction never delivers happiness, but instead creates misery in spades.
