Snarkily, he demands to know how the poor dare to use cell-phones. They're poor! Let them...you know...use payphones.
Most of the comments point out that cellphones are cheap, idiot, and homeless guys need them if they're ever going to get unhomeless (how can you look for a job without a phone, tool?), but a few chime in to rattle their rich Rethug sabers: no one who owns a cellphone is poor! America: the only country in the world where the poor people are fat! Har-har-har!
I'd like every one of those commenters to spend five years in the Arkansas hills in the bad half of a duplex on minimum wage and no fucking health insurance. Driving a ten year old Dodge Ram pickup with busted windshield wipers. See how their tune has changed at the end of that little experiment. Har-har-har.
