Paul's "job" explains why the thought of earning $26,000/year seemed so out of his reach. He is hauling bales of hay and picking up cow pies part time--and apparently not doing a good job. His employer said he was probably not going to keep Paul on much longer. Paul's people skills are so poor that he thought he was a valuable employee--he began his resignation speech apologetically, as if the farmer was going to be upset to lose his services. If he was working for Father in the past, it must have come as a shock to have to work part-time for the farmer because he left Brazil to earn money. How much could he possibly be making as a part-time assistant cow shit wrangler? I think something happened to Father or perhaps to Father and Mother's marriage while Pole was in Brazil, and Pole didn't find out about it until he came back to the US. Maybe Father died, or got very sick, or left Mother, or just got fed up with Pole.
Pole is in a world of trouble. His felony conviction(s) are making it hard to find work, and his awkwardness in general makes it unlikely that he would be able to talk someone into at least giving him a chance, despite his criminal record. I think psychological help is a good idea, if he could afford it, although it's probably too late. Career counseling is another good suggestion, but again, he is so damn awkward (dare I say loony?) that I doubt that would make any difference. He doesn't speak Portuguese, so his chances of finding employment in Brazil are not good--he said he was going to find a job teaching English, but I don't know how he could get through the hiring interview in Brazil, either. And what a terrible temperament for a teacher!
Yeah, he's screwed. As are Karine and their baby.
