Sears’ lowest-priced 10-inch table saw: 52.35 hours of work required in 1975; 7.34 hours of work required in 2006.

Sears’ lowest-priced gasoline-powered lawn mower: 13.14 hours of work required in 1975 (to buy a lawn-mower that cuts a 20-inch swathe); 8.56 hours of work required in 2006 (to buy a lawn-mower that cuts a 22-inch swathe. Sears no longer sells a power mower that cuts a swathe smaller than 22 inches.)
