You think you need your job. But I've lived abroad as a vagrant, abstaining from my own money to rely on the charity of strangers. Most were beggars themselves, yet they were happy, and So, for that summer, was I. Your job needs you, not the other way around.
This is a quotation from Severance, a latest TV show.
The sentence "most were beggars themselves" is incomprehensible to me. "Most" here is, in my view, a pronoun referring to the strangers. And as a whole I assume this line indicates that the author was given money by strangers who are also vagrants like the author. But the following sentence "yet they were happy" is not coherent with the former. Is it because they are happy about helping each other? This logic doesn't sound convincing, at least to me.
