Lots of factors:
1) Professionalization of casual labor, as noted above (“guys with snowblowers and pickup trucks”)
2) Increased time demands on K-12 age kids (homework, activities)
3) Reduction in adult availability to find and supervise kids doing such work:
3a) face it, if you hire a 12-year old to mow your lawn, you’re going to have to go out and get the bits he didn’t get to
3b) a lot of hiring kids in this way comes from knowing your neighbors (and their kids)
etc. etc.
3a(i) Homeowner liability. Twelve-year olds have no business running a (crappy) lawnmower.
