<human>: Hey all, firstly thanks for reading (first-time post, here!).

As a brief history (though the title sums it up):
My 23 year old brother did not graduate from high school (dropped out as soon as it was possible) and has since never held a job, has limited social interactions with anyone other than a transient core group of 1-3 friends and our mother, and has made no progression within the 6 years since dropping out to do... anything.

Meanwhile, our mother works 50-80 hours/week to cover living and luxury expenses for him (which pretty much consists of video games).  Playing the tough love card of "shape up or ship out" isn't really an option with him, since he has no means of helping himself to survive.

Has anyone else experienced something related or similar?  

Is there anything I can do to aid him in becoming a responsible adult?

Can you condense the text into a few key points?
<bot>: My brother has no motivation to do anything other than play video games and leech off the parental unit.  Help.
