Technology. Imo your buddy needs a pair of those 'knives that cut bricks' to last him instead of a sharpening/whet(sp?) stone.
Realistically as Agayek said above; if I get a hole in a sock it's easier to take 10 minutes to buy a new pair opposed to getting out your sewing materials and stitching it back up.
However as for the social/mental benefits of doin' it yerself(ikno) obviously getting satisfaction from self accomplishments motivate individuals differently, I don't think everyone is as stupid as they say they are.
Most basic life skills, sharpening a stone, stitching clothing are pretty self evident on how to accomplish; whether you're a master anyone with basic reasoning can say if I stab thread between cloth I can patch a 'hole'. Distinguish 'Master' ability from 'can get it done'. I can't cook for crap, but I know if I throw meat on fire long enough it'll cook through, and salads are a flawless victory
