Okay sure but most people with a steady 9 to 5 aren't buying industrial volumes of crack. Poverty creates big demand for the worst of the drug trade. Moreover, the drug dealers who are earning big exploiting this aren't going to be found in the worst parts of the city. The police are at best picking up the low- to mid-level distributors. "Broken Windows" has failed to win the drug war for decades; if you want to keep backing a failed experiment you're welcome to it, but I'm going to seek an improvement.
