I “sold” religion door-to-door in Brazil two decades ago and I know it annoyed a lot of people. But this fantastic long-read on for-profit door-to-door salesmen makes me feel slimy because these guys are a nuisance and largely dishonest. The problem with door-to-door product sales is that many (most?) harbor the dishonest believe that every household needs what they’re selling. That’s just not true. But because of the rise of spam lists and not call registers, door-to-door sales are actually growing. Hustle always works. And so does taking advantage of mentally feeble buyers.
