Chris has no chance at this point. Even if he wasn't autistic AND stupid, he has no social skills, no technical skills, no intellectual skills, and no basic work ethic.
You're kidding yourself.
I agree with you, but not entirely. I think, if Chris was faced with the prospect of "Get a Job" or "Become Homeless" and those are his only two choices, I think he could possibly succeed in getting a job. It wouldn't be a good job, by any means, he's not skilled enough, and like you said, he's lazy, so I doubt he go far in the way of promotion, but he would be employed. Then, theoretically, if he didn't get himself fired, through social interaction with co-workers (and most likely customers, since his job would likely be in the service industry), he might gain some maturity to the point of living an average life. Who knows? He might even clean himself up a little and finally get that sweetheart. It's possible. It would require serious effort on his part, not only just effort in work ethic, but effort in filtering his own thoughts.
Because, and I don't relish the thought of this at all, when Barb dies, this may very well be a choice Chris will have to make.
Now, if we base what Chris will do in the future based on what he's done in the past, he will try to keep his status quo for as long as he can until he becomes destitute and is raving out on the streets about how this is all the fault of "THOSE DANG DIRTY TROLLS!" while he begs for spare change out of a McDonald's cup.
But you know, I actually hope better for him. I hope when push literally comes to shove, he takes the difficult, but ultimately more rewarding path.
