The disease model is convenient to liberals because it spares them having to say negative things about poor communities. But this conception of addiction harms the very people we wish to help.
Because they can’t draw unfavorable inferences about life in poor ghettos or poor rural communities (to which they have little exposure), liberals are drawn to the belief that drugs cause addiction.
I couldn’t disagree more. But as a card-carrying liberal myself, I’ll swallow my bile and try to understand.
