Libraries are a poor analogy, and you know it. Americans, sadly, are much less interested in books that other entertainment mediums these days.
Also I do not see huge crowds on free sidewalks.
In the urban centers I visit, the sidewalks always seem very crowded to me.
On the subject of wages; I see no problem with toll collectors getting $20/hr if they can get it. Wages are in essence an agreement between the buyer (employer) and seller (employee) of a service for an agreed-upon price. If the seller can get more for their skill, more power to them. If the buyer can get the same service cheaper elsewhere, bully on them as well. It's where wages are dictated by external influences that I have a problem: The minimum wage, for one, keeps wages artificially high. On the other hand, the influx if illegal foreign labor keeps wages artificially low. This leads to what we see now: A continually shrinking middle class.
That is very true.
I asked a worker at Wal Marts where they had moved their children's books too and she said they hadn't been moved. I had her follow me over to the isle and pointed to the display. All there was there, was those books where you push different a buttons on the cover, and coloring books.
I asked her why was there was no selection in children's books, you know what she said? Kids don't read anymore like they used too.
I guess they thought it was a waste of space and took more than 2/3 of them out.
It was not analogy. It was direct test of your "rule that when a resource is given away for free, demand will swell to consume all available supply"
