I'm missing the connection between addiction and Economics..? Unless you're saying getting hooked and giving money to the dealers will stimulate the economy, in which case you're really just helping criminals instead of honest workers. Not to mention addicts can go to extreme lengths to get their fix, so they'll end up stealing from people in a lot of cases.
I am comparing QE to economic heroin.
To be completely honest, this actually doesn't seem like a bad comparison. There is a seemingly unspoken urge to fix the economy by dumping more money into it.
Cooldgamer is basically spot on with the similarities between the two.
