When people constipate, they take laxatives to let "them" go. It is the same case for the economic constipation. Its bowels are stucked with toxic assests.

Just as most other shops, these sanitary shops are facing a grim sales prospect because there are simply fewer home buyers. No wonder the shopkeeper looks puzzled.
Just in case you wonder, I took this photo while traveling on the upper deck of the bus with, of course, my GX200 :)
