The fact that he's a dog walker kind of hits home to me. A couple of my lefty friends were dog walkers about 9 years ago. They didn't make very much money, but for what they were doing with their lives at the time, it met their needs. Both of them decided to try and get better jobs, but everything they were qualified for was a side-grade at best. When they realized they were stuck, they combined their savings and started their own business that went into rich neighborhoods and picked up dog shit out of people's yards. Almost a decade later, they rent an office space, own 6 trucks, have 8 employees, serve 400+ clients, and both of them pull a 6 figure salary while only doing 3-4 hours of paperwork a day to keep it all running. Even though they're successful, they've hung onto a lot of their lefty ideology, so their workers get paid more than minimum wage, get to pocket their tips, paid time off, and medical insurance where the company pays out 75% on claims.
Having a shitty job isn't a dead end if you have a little bit of balls and motivation. Doreen is fucked because they're A) irreparably lazy, and B) unwilling to self-advance because they've developed a hatred for anyone that generates capital. I'd be shocked if they haven't had opportunities to do better, but refused to do so because they'd see themselves as selling out to the "man." Trannies love being in a constant state of oppression, and will often sabotage themselves to maintain their lower class status.
