In the urban hellhole we have jackhammers. In the suburban paradise, leaf blowers. Yesterday, as the guy rounded the corner, I said to myself "It may be deafening, but at least this one guy is doing the work that, a generation or so ago, would have required four or five workers with rakes. No doubt he is being paid a wage that reflects his increased productivity, while the business that employs him also earns additional profits as a result of this technical innovation. Isn't America great!"
