Yeah, but it's about an year that I follow Chris Chan and I thought that it's really sad what happened to him, also the financhu saga is getting really boring, so I figured out that maybe if she gets a job she could grow out of the apocalypse cult nonsense and start becoming a decent human being.
Okay. Quick, blunt answers to your points.
1. The Financhu Saga will
never end short of a surprise lottery win of immense size or some mysterious multi-millionaire rich uncle dying and leaving the lot to Chris. Both he and Barb have shown no real ability with budgeting or money in general and refuse to do so. Any money coming into the house goes to bills, nutritious bananas, Lego, and vidya. Saving is not a thing for these people. At all.
2. Getting a job? Not bloody likely. It was Bob, long, long ago, who told Chris that he'd always be better off with a monthly tugboat than getting a job. The two times that Chris did get a job, back in arguably much saner days for him, he promptly lost both, lasting only a few weeks in the longer-lasting one (Wendy's). In addition, Chris has become ever more entitled, and now genuinely believes that work is beneath him. Short of press-ganging him onto a treadmill, ain't gonna happen.
3. We don't go along with his CPU/Dimensional Merge bullshit. We debunk it and laugh at it. It's fun. Chris, however, wants to believe that it's all true, and as a result it's again nigh impossible to change his mind about this. The likes of the Idea Guys and Sockness may have nurtured this delusion, but in all fairness it's been Chris's own doing ever since he first set out his belief in a Roger Rabbit Universe.
Most importantly, in summing up, Chris is lazy, autistic, entitled, egotistical, stupid - and, despite all this, just self-aware enough that he's in increasing desperation about the state of his existence, and accordingly armours himself in fantasy all the more fervently.
Maybe, if he'd been caught long enough ago (decades or so), his life could have been turned around productively into something better, more security, more self-esteem, more contentment. Sadly, that particular tugboat has long since sailed.
TL: DR - Chris will never get out of financial trouble, never get another job, and will go to his grave babbling that the Dimensional Merge is real. Sad, but - short of a literal miracle or several - true.
