Question Author
I'm far from stupid, and only mildly prejudiced.
A few points:
-You are wrong in assuming these vendors go and choose their own merchandise - they obviously operate from a central 'distribution' point, otherwise they wouldn't all be vending the same things, the length and breadth of Britain! (I also doubt very much whether they pay up front for goods; I'm sure they work on a sale-or-return system, taking some commission.)
-many of the things I suggest would have very low wholesale prices - crsips from a local supermarket could be offered door-to-door with a 200% mark up.
-a Big Issue vendor doesn't try and sell encyclopaedia because walking home from work his/her customers don't want a multi-volume reference work, but might want something to read on the Tube. In other words, they offer what there is a market for, unlike their door-to-door brethren.
-It isn't a question of my 'Humanity' (sic). I'd like to see these people sell more successfully, but have never understood why they market such inappropriate products.
Unfortunately for you, my reasoned and intelligent reply now makes your hyperbolic assertions of my stupidity rather childish, and your interpetation of the issues at stake extremely naive. Still, this thread died about two weeks ago so I doubt anyone at all will read this...
