A recent commenter led me to an out of date blog about street vendors that had me rapt for quite some time. New York street vendors are an integral part of the fabric of our streets, and I never realized how much I take them for granted until I read this blog. Of particular interest is the history of the Senegalese vendors, and how they came to corner the umbrella market.
My Junior High School social studies teacher taught us the lesson of supply and demand by recounting his personal story of selling umbrellas while it was raining so he could charge double. In fact it was the only lesson this particular teacher ever made that was original, and did not use an overhead projector. But I digress. As usual.
