Buying a plane ticket sounds impossible for someone without a job, but you would be surprised how much money you can make by busking, day labor, or just straight up begging. I've made over $100 in 2 hours just from flailing on a cheap guitar in a busy location.
Sure, I had to have a skill to begin with, but saying you can't do it is wrong. Just most people won't do it because they think they can't do it.
Outside of America, maybe, but most people in America live close to a gas station or a highway intersection.
My income quote comes from a gas station in a backwater town in the deep woods of Alabama, and I'm not a great guitarist or something amazing worth throwing money at.
Yeah I'm not a busker myself but I've found "middle America" and more humble populations to be more generous in general. It's not the rich who typically empathize with someone on the street, it's a working class person who's been there.
Sounds like you're talking about a one-time thing then rather than a sustainable practice. I think if you loiter in front of a gas station you will be rousted by police in much less than a week.
