When I started my Depression era tramps reading,
sovay recommended the 1933 pre-Code film
Wild Boys of the Road as must-see viewing.
This is absolutely accurate.
Wild Boys of the Road is dynamite, and I wish it were better known. It tells the story of two ordinary high school students, Tommy and Eddie, who drive onto the scene in Eddie’s rattletrap car painted, all over with twenties-style slogans: “Four wheels, no brakes,” “Out hunting: mostly teddies.” (Teddies were a kind of women’s underwear at the time.)
But their carefree days are numbered: Eddie’s widowed mother is already struggling, so that Eddie doesn’t even have the entry fee to the dance (Eddie sneaks in cross-dressed in his girlfriend’s hat and coat, as girls don’t need to pay), and Tommy soon learns that his father has lost his job. Unable to find work in their hometown and eager to ease the burden on their beleaguered parents, the two boys impulsively decide to jump a train out of town - and quickly meet Sally, a girl tramp, who is traveling to Chicago to meet her aunt.
Sally is a bright-eyed, freckle-faced youngster, more or less what would happen if Anne of Green Gables had to ride the rails. When she first meets the boys, they think she’s just stolen their sandwiches, and Sally gives Tommy a bloody nose, which of course makes them fast friends as soon as Tommy realizes she is (a) a girl, so they have to stop fighting, and (b) not a sandwich thief.
Unfortunately, Sally’s aunt gets arrested for prostitution almost as soon as the kids reach her apartment, so they have to hit the road again (Eddie pauses to carry along a chocolate cake).
They quickly fall in with a big group of kid tramps, and the camaraderie among the kids keeps the picture from ever seeming like sheer misery porn, but nonetheless it's clear their lives are grim. A railroad guard rapes one of the girl tramps; the rest of the kids band together to fling the man off the train to his death. Eddie loses a leg when he falls across a train track and the train runs over it. Even when the kids have a bit of luck, like setting up a sort of village in a bunch of unused concrete pipes, the police chase them out with firehoses. The man who owns the pipes gave the kids permission to live there - but the city thinks they’re a nuisance, “wild boys of the road” as a headline puts it, treating them as vicious young hoodlums when really they’re just kids whose families have fallen on hard times.
The main characters are played by actual teenagers, and so, I suspect, are most of the other kid tramps in the movie. The movie is a strong argument in favor of having actual teenagers play teens, instead of having them played by twenty-somethings: their misfortunes hit differently when you can very clearly see these characters are baby-faced round-cheeked wide-eyed kids.
