Sayeth Adam Smith:

"The whole of the advantages and disadvantages of the different employments of labour and stock must, in the same neighborhood, be either perfectly equal or continually tending toward equality."

"[Milwaukee Metropolitan Sewer District] is now paying an average of $460 a day for one worker to scoop spent condoms from the surface of tanks at Jones Island [treatment plant]."

Yucky story here. And it does get worse, especially the part about what a fisherman saw in Lake Michigan.
