Dear Simon Pitt,
You have excellently analysed and presented the facts and the situation. It was enjoyable to read and also it made me to ponder over "free lunch".
After thinking a little, I feel that the situation developed naturally to become like that of fish and the bait. Each one of us who thinks that there can be a free lunch is behaving like a fish upon having come across a bait. Those who want to go on behaving like fish would continue to make enough sea food available to those are fish catchers but I strongly feel that there will also be excellent demand for paid lunches, provided there are some daring provider of the paid lunches.
