Can you help me with the assignment for the topic "Corporate American and Crack Dealing Industry" of chapter 3 "Why drug dealers still live with their moms?" of the book "Freakonomics" by Steven Levitt. Previous tutors gave a summary of ch3 in whole, but I need an explanation and connection between "Corporate American and Crack Dealing Industry"
